For sensing company Provizio, it’s the only way the transportation industry should introduce autonomous vehicles. In Provizio’s view, using AV building blocks – technology such as automatic emergency braking and lane-keep assist – can be valuable in ADAS systems, but they should not be used to drive vehicles until the perception problem has been solved.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzAyMjgyNDM3MTM3LXByb3ZpemlvLXJhZGFyLXN1cGVyLXJlc29sdXRpb24tZ2FsbGVyeS5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib">An example image using data taken from Provizio’s “super-resolution” radar sensor.<blockquote>“It’s not that we’re skeptical about autonomous driving, it’s just that we strongly believe that the industry has taken this wrong path,” Dane Mitrev, machine learning engineer at Provizio, told SAE at September 2023’s AutoSens Brussels conference.</blockquote>“The industry has looked at things the other way around. They tried to solve autonomy first, without looking at accident prevention and simpler ADAS systems. We are building a perception technology which will first eliminate road fatalities, then deliver next-generation ADAS – and then solve autonomy. We believe that’s the right order.”Obviously, the industry is in favor of AVs. A group of 11 mobility and automotive companies released a 157-page paper in 2019 called “Safety First for Automated Driving.” Those companies — Aptiv, Audi, Baidu, BMW, Continental, Daimler, FCA US LLC, HERE, Infineon, Intel and Volkswagen — used the paper to propose a non-binding organized framework focused on “the development, testing and validation of safe automated passenger vehicles,” but did not attempt to establish any actual limits on what companies could do as they developed AVs. In the years since, AV technology has continued to advance, but not with the mission to solve sensing and important safety issues before teaching the vehicles how to maneuver.Provizio’s solution is its 5D Perception driving platform, named for the way it uses five different inputs to sense the environment. There’s the 3D radar information of an object in space, plus velocity information, plus the fifth dimension: perception, which means AI embedded in the hardware. Mitrev said the final vision of this technology will be powered by radar and cameras, not light detection and ranging (lidar). Radar’s benefits are well known: the sensors are smaller (and thus simpler to integrate) and less expensive than lidar and can see in all weather conditions. For now, though, Provizio is working with lidar, especially around its hometown.<h3>Irish sensors are smiling</h3>Provizio is headquartered in Limerick, Ireland, and has offices in North Ireland and Pittsburgh, Pennsylvania. In late 2022, Provizio signed a deal with micromobility company Voi to test 5D perception on Voi’s scooters. Alongside potential OEM and Tier 1 partnerships he couldn’t discuss, Mitrev said Provizio also has a partnership with Jaguar Land Rover, supporting tests at a future mobility campus in Ireland.These real-world tests involve collecting data from lidar to train the new radar AI. Provizio synchronizes the lidar and radar sensors, then extracts value from the lidar data at training time, embedding it into the neural net and teaching the neural networks based on these data streams. Imagine lidar as an old professor teaching a young radar sensor a few things, but sooner or later, the student – Provizio’s radar – won’t need the teacher anymore.<blockquote>“We lean fully towards a lidar-less path,” he said. “Lidars should not be involved, even in [SAE Level 5] vehicles. They’re not necessary.”</blockquote>The same is not true for cameras. To understand semantic information such as traffic signs, Provizio’s system uses cameras to augment the radar data.“Provizio is a perception company, first of all,” Mitrev said. “We are not a radar company. We’re not a car manufacturer. We’re a perception company, we have this radar and we have a perception platform that fuses radars and cameras and provides this low-cost solution.”Provizio was founded by Barry Lunn following the acquisition of his company Arralis, which focused on millimeter-wave communication technology for satellite communications and aerospace markets. Provizio’s radar technology grew out of radar work Lunn was familiar with in the aerospace industry. Instead of a commercial, off-the-shelf radar unit, Provizio is “redefining radars,” Mitrev said, by adding AI neural networks to the radar GPUs so all critical decisions can be made on the radar itself with less than five milliseconds latency to make those decisions. He said Provizio’s goal for its 5D radar is to see up to 600 m (1,969 feet) in 360 degrees in all weather conditions.<blockquote>“Once we have this 5D perception, there is literally no reason to build any other system that will do ADAS or autonomy,” he said, adding that accident prevention is “something tangible that we can solve in the next one, three-to-five, years.”</blockquote>At CES 2023, Provizio said it planned to deliver the first of its 5D Perception platforms by 2025. Provizio’s commercial strategy relies on licensing its technology to Tier 1 suppliers and OEMs. Once better sensors are in more vehicles that accurately understand the world around them, that’s when we can start letting vehicles drive themselves, Mitrev said.“The end goal is mass adoption, to have our 5D perception on all vehicles or a lot of vehicles worldwide, then we bring down the road deaths,” he said. “We believe that this is the right path. The industry has taken this the other way around. [Starting by building a self-driving car] is just too complex, let alone with only cameras, as some companies claim.”

Provizio offered demo drives of its technology on the road in Las Vegas during CES in January 2023. These images show some of what the sensors saw during the drive, along with some of Provizio’s identifying data. (Provizio)

Lidar vs Radar: Key Differences, Specs and Uses in Autonomous Driving and Speed Enforcement

It takes a radar out of the ordinary to catch a drone in flight. It is even harder to detect a drone that is hovering in the same place, because it quickly disappears in the background noise. But a new radar system&mdash;developed by researchers from DTU Space in collaboration with the Danish company Terma&mdash;can do both and more to boot.The radar has a high resolution and a wide field of vision, and it can track many drones simultaneously. Drones are otherwise difficult to spot, because they can be tiny and come from all directions. Moreover, they are often made of plastic materials that do not reflect radar waves very well.&ldquo;There is a large market for detecting drones, for example in military contexts and at airports,&rdquo; says Professor J&oslash;rgen Dall from DTU Space, who heads the radar project. He also mentions the problems that the Swedish authorities have had with illegal drone flights. Especially at the beginning of 2022, drones were repeatedly observed over nuclear power plants, military areas, airports, and royal palaces.To avoid accidents at airports, protect critical infrastructure, and keep military secrets, etc., there are many places where drones are not allowed to fly. The first step towards combating illegal drone flying is to detect, track, and preferably also classify the drone. And here the new radar can help.<h2>Many antennas provide higher resolution</h2>In general, a radar works by emitting a microwave signal that is reflected by an object, and the echo is then picked up and compared with the outgoing signal. Knowing that the signal moves at the speed of light, it is easy to calculate the distance to the object. You just have to measure how long it has been under way.This is easy in theory, but it is more difficult in the real world, especially if you want to know not only the distance to an object, but also its exact position in three dimensions, as well as its speed. But here the researchers from DTU Space exploit the great advantage of having a radar which has not just one antenna that is used to send and receive signals, but instead a total of 16 antennas.The principle of using multiple antennas is called MIMO, which stands for multiple-input multiple-output. The principle is especially known from wireless communication, where the advantage is first and foremost to ensure a high bandwidth.Without MIMO technology in the latest WiFi standards and mobile networks (4G and 5G), the speed of data transfer to and from the laptop and mobile phone would be somewhat lower than it is today. The DTU researchers set out to examine whether the technology with multiple antennas can also be used to improve radar systems, and this turned out to be the case.<h2>Works without rotating</h2>&quot;With MIMO, we can see in all directions concurrently within a fairly wide angle range&mdash;for example 120 degrees&mdash;and we can get a good horizontal angle resolution in a relatively low-cost way without rotating the radar,&rdquo; says J&oslash;rgen Dall and continues:&ldquo;Our radar has eight transmitters and eight receivers. If all the transmitters sent the same signal at the same time, we would just get one large antenna sending a signal in a specific direction, but, instead, we make sure that the transmitters either send the same signal in a staggered manner or send different signals.&rdquo;&quot;Each of the eight signals is collected and separated from each other by all eight receivers, which gives us 64 virtual channels in total, even though we only have 16 physical channels.&rdquo;When a drone is hit by a signal from a transmitter, the signal is reflected back to all eight receivers, and&mdash;based on the timing of the echo&mdash;the distance and direction to the drone can be calculated. But with eight transmitters and receivers positioned in just the right way relative to each other, the position and speed of the drone can be determined much more accurately.<h2>Range may be increased</h2>If the drone is close, it even becomes possible to identify the type. So-called micro-doppler signatures&mdash;which are caused by the movements of the rotor blades&mdash;can reveal what type of drone it is.The radar project has been running since 2018 and has now resulted in a demonstration model that clearly shows that the concept works. Another MIMO radar is being built. The range of the prototypes is just 100 metres, because a longer range requires higher power, a transmission permit from the authorities, as well as somewhat more expensive amplifiers. Initially, the project focused on showing that the technology can be used, and the range can easily be increased in later versions.J&oslash;rgen Dall also emphasizes that MIMO radars can be used for other purposes than detecting small, flying objects. The primary purpose of the project is to conduct research into radar technology, and drone detection was an appropriate application in this connection.The project will continue with two PhD students attached and a third on the way, and it is primarily funded through a grant of DKK 5.8 million from the Thomas B. Thrige Foundation. If Terma chooses to continue with the technology for actual product development and commercialization of MIMO radars, it is possible that these systems will contribute to protection of airport security against threats from the ground as well as the air, as a competence extension to Terma&rsquo;s airport radars worldwide.

</style>The market demand for smart devices and their applications is experiencing dynamic growth as more and more consumers are looking to leverage the comfort, energy efficiency, and security benefits of smart technologies. According to <a href="https://www.statista.com/statistics/976313/global-iot-market-size/" target="_blank">Statista market research the global IoT&nbsp;market</a> will be worth around 1.6 trillion US dollars by 2025.&nbsp;One of the factors that propels this market growth is the emerging wave of &ldquo;intuitive sensing&rdquo; applications, which enable humans to interact with smart devices in a more natural and seamless way than ever before. The deployment of intuitive sensing relies on a range of non-intrusive sensing systems, which endow IoT applications with novel perceptive capabilities. Intuitive sensing systems enable IoT applications to &ldquo;see&rdquo;, &ldquo;hear&rdquo;, &ldquo;smell&rdquo;, &ldquo;perceive&rdquo; and understand the surrounding environment. In this way, they open new horizons for IoT technology in a variety of areas such as smart homes, security and industry.<h2>Introducing Radar Sensors</h2>In the scope of IoT systems and applications, a radar sensor is a device that is capable of sensing and potentially tracking one or more objects. In contrast to other Radio Frequency (RF) based passive/active wireless sensor systems, radar sensors are active, i.e., they can send out pulses and receive their echoes. Radar technology makes it possible to estimate the target&rsquo;s speed, direction, and range (i.e., distance from the radar transmitter/receiver). Moreover, there are radar sensors that can detect small movements and even the presence of humans due to their high sensitivity towards the smallest motions.Overall, the key advantages of highly sensitive radar technology for IoT applications include:&nbsp;<ul><li>Small size: Radar sensors have a small footprint in the size of the overall IoT system. Therefore, they enable the development of IoT systems of relatively small size. Their small size boosts their unobtrusive operation so as not to disturb or distract users.</li><li>Robustness: &nbsp;Radar sensors work very well under different environmental or climate conditions. For instance, their operation is not essentially affected by variations in temperature or lighting conditions. &nbsp;</li><li>Product Design Flexibility: One of the key features of radar sensors is that they can be concealed under product covers, which increases the design and deployment flexibility for IoT products. Specifically, radars emit RF signals at high frequencies (e.g., 24GHz), which can pass through most materials (e.g., plastic, glass, and wood). Hence, they can provide accurate readings for objects behind walls or obstacles.&nbsp;</li><li>Sensitivity: &nbsp;Radar sensors can detect very small motions (e.g., breathing movements), which enables a host of interesting IoT use cases like sensing of human presence and of vital signs such as heartbeats.</li><li>Power efficiency: Radar sensors consume relatively little power and therefore allow for great battery life. Hence, they enable IoT applications with considerable autonomy and energy efficiency.</li></ul><h2>Benefits of Radar Sensors for Motion Detection</h2>Based on the above-listed properties, radar sensors can be used in many possible scenarios. However, their most common application is to detect movements and the presence (or absence) of targets such as people, vehicles, and animals. &nbsp;Motion detection is an important capability for many IoT applications, including security monitoring, energy management, human-computer interaction (e.g., gesture recognition), and medical monitoring i.e., tracking of heart and respiration rate.&nbsp;The technology traditionally used for motion detection is passive infrared (PIR) sensors. Passive infrared motion sensors have been commonly used for detecting people moving around a space. They have been around for decades and have become ubiquitous i.e., they can be found in lighting fixtures, security systems, and automatic doors, among other places.However, there are significant limitations associated with the deployment and use of PIR sensors, such as false alarms due to pets and other sources of infrared radiation in the environment, interference from other sources that operate on the same frequency range (e.g., TV remote control), limited sensing range and lack of directional information. Specifically, PIR sensors require a direct line of sight to detect motion, and their detection range is limited to the area directly in front of the sensor. Also, they usually require a significant movement in order to be triggered. For instance, it&rsquo;s quite common for users to wave their hand in front of a PIR sensor in order to ensure that a smart home command is understood. &nbsp;Radar technology alleviates the above-listed problems and limitations for motion detection. For example, radar sensors enable IoT applications to reliably tell the presence or absence of people in a room, independently of how fast and how much they are moving. Moreover, radar sensors are so precise that they can detect a human&#39;s breathing or heartbeat. This is not possible with PIR sensors that can only detect temperature changes caused by objects passing through their field of view.&nbsp;<h2>60GHz Radar Technology</h2>Radar sensors operate in different frequencies. A rich set of radar technologies operate at 24GHz with the bandwidth for FMCW (Frequency Modulated Continuous Wave) radar operations covering up to 250MHz within the regulated ISM (Industrial, Scientific, and Medical) band. This technology is extensively used in outdoor use cases, since it offers high detection range and is very robust to environmental influences (e.g., humidity).While the 24GHz band is limited to the ISM band, there is a 7GHz unregulated bandwidth available around 60GHz. Hence, 60GHz radar technology has been developed to help create more powerful applications and products, notably applications requiring large bandwidth operations and close proximity sensing applications. Specifically, 60GHz radar technology can detect motions and complex gestures at a finer level of granularity and with better accuracy than 24GHz technology. &nbsp;This makes 60GHz technology an ideal choice for use in applications like occupancy sensing, human tracking, and segmentation, materials classification, as well as monitoring of human vital signs at a distance. Moreover, the micro-motion detection capabilities of 60GHz radar technologies make it appropriate for the emerging wave of Augmented Reality (AR) and Virtual Reality (VR) applications that will empower the Metaverse. This is the reason why 60GHz radar chipsets are already being integrated into HMDs (Head Mounted Displays) by various manufacturers.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjUzMzkwMDYyMjk5LWxhdXJlbnMtZGVya3MtYkNkSXg1TGpyWW8tdW5zcGxhc2ggKDEpLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 788px;" class="fr-fic fr-dib">60GHz radar chipsets are already being integrated into HMDs (Head Mounted Displays) by various manufacturers.&nbsp;<h2>Radar Technology in Smart Home Applications</h2>Smart homes represent one of the fastest-growing segments of the IoT market. It is also the segment where radar technology acts as a catalyst for improving applications&rsquo; functionalities, accuracy, energy consumption, and cost. Specifically, the emerging availability of low-cost, low-power radar sensors enables a new generation of smart home applications ranging from enhanced security and safety through to improved convenience and comfort. Some of the most prominent examples of radar-enabled functionalities in smart homes include:<ul><li>Automatic Door Control: Radar sensors for intuitive sensing provide not only information on motion but also on approaching and departing movements. This can enable automatic door control applications, where doors open only if a target is continuously approaching, and not when other kinds of motion are detected.</li><li>Presence/Absence Detection: When equipped with radar sensors, smart devices can sense the presence or movement of people, which enables a wide range of optimization applications. For instance, when no one is present, a radar-based smart device can automatically switch to sleep mode and save energy.</li><li>Segmentation and Tracking: &nbsp;Radar sensors can add many smart functionalities to devices such as sound systems. For instance, sound systems could track the position of the listener and continuously optimize volume and sound parameters accordingly.</li><li>Elderly Care Systems: Radar technology enables the development of innovative elderly care applications. For instance, they empower bed-exit systems that can be used to tell if a person has got out of bed and not returned within a few minutes. Similarly, radar sensors enable chair exit systems that determine whether a person has left their chair and not returned within a certain time.</li><li>Heating Control Systems: Radars enable underfloor heating system control that determine whether someone is in the room, turning the heating on or off accordingly. &nbsp;In addition, they can track the distance and the position of a person in a room towards adjusting the fan speed as well as the direction of the blades of the room air conditioner unit. Such use cases improve the occupants&rsquo; comfort while boosting environment performance and sustainability.</li><li>Fall Detection: &nbsp;Radar-based systems can be used for fall detection. In this case, the radar is typically mounted on a wall or ceiling and is continuously emitting modulated signals. When a person falls, their body rotates, causing shifts in the reflected waves. The radar system can then detect these shifts and record them as a fall event.</li><li>Vital Signs Monitoring: Similar radar configurations can be also used to monitor breathing patterns and heart rates. Over time, this information can be used to detect deviations in the heartbeat pattern that could indicate cardiac arrhythmia or other problems. Heartbeat pattern detection enables a host of innovative lifesaving applications in the areas of infant care (e.g., identification of irregularities in heath rate) and elderly care.&nbsp;</li></ul>Most of these functionalities can be captured based on body movement at a distance, even in poor lighting conditions. Moreover, they are delivered in a non-intrusive manner for the home&rsquo;s occupants. The latter can move freely around the house without tripping false alarms from optical motion detectors mounted on walls or ceilings.&nbsp;<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjUzMzg5NDExMjc1LXJhZGFyIHZpdGFsIHNpZ25zLmpmaWYiLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 788px;" class="fr-fic fr-dib">Radar has applications in vital signs monitoring.
