A 60GHz radar sensor for horizontal and vertical distance and velocity measurements.

Infineon BGT60TR13C Radar Sensor

<h2>High Precision Antennas with Low Power Consumption</h2>The BGT60TR13C MMIC radar sensor operates on 1.8 Volts, consuming up to 200mA current. The antenna can work on ultra-wide bandwidths thanks to its Frequency Modulated Continuous Wave (FMCW) operations. Its small packaging and integration with a finite-state machine ensure low power consumption.&nbsp;The power consumption is 5mW or less as the sensor can be optimized to work in various power modes. With proper duty cycling, users can reduce power consumption to even lower levels. The FMCW operation capability allows the radar sensor to perform frequency sweeps and store sampled data in its autonomous FIFO memory. Moreover, the Finite State Machine (FSM) makes it a flexible option to configure frequency modulations and optimize various power modes.&nbsp;While working in the 1.8 V power domains, the radar sensor can operate in five domains, i.e.,<ul><li>Analog Domain</li><li>Digital Domain</li><li>Radio Frequency Domain</li><li>Voltage Controlled Oscillator</li><li>Phase-Locked Loop (PLL)</li></ul>Moreover, it offers an optional 3.3V operational domain for loop filters (LF) that regulates the maximum VCO frequency and sensor bandwidth according to the supply voltage.The antenna array helps measure vertical and horizontal distances, velocity, and angles. Its lower power applications make it suitable for wearable devices, enhancing its applications in healthcare, security systems, and sensor-based infrastructures.&nbsp;<h2>Sensitive Antenna for Applications in Wearables and Movement Detection Systems</h2>The Infineon BGT60TR13C features a set of four antennas. A transmitter (Tx) and three high-sensitivity receiver antennas (Rx) can detect sub-millimetre movements. Thanks to high bandwidth operation of more than 5GHz, the antenna array has a high resolution of close to 3cm.&nbsp;Due to high sensitivity, the BGT60TR13C becomes suitable for detecting minor movements and pulses. With a ramp-up speed of MHz per microsecond, it provides a high doppler velocity. Its high signal-to-noise ratio (SNR) allows the antenna array to see a person 15 meters away when the antenna is facing the front.&nbsp;The sensor mimics Passive Infrared (PIR) principle, making it more precise, detecting micro-level movements such as pulses and other body vitals like heartbeats, chest movement and eyelash twitches. Due to such high accuracy and precision, the antenna array can substitute high-resolution cameras that require complex algorithms and considerably more power for detecting the same movements.&nbsp;The detected movements can be read through a microcontroller. For nominal use, the user must initially configure the sensor through the Serial Peripheral Interface (SPI) and then process the signals per the requirements.&nbsp;The Infineon BGT60TR13C is suitable for various applications due to its intuitive sensing capability. It has many uses in wearable devices such as People tracking, Smart home sensor applications, people counting mechanisms, sleep monitoring devices, presence detectors, elderly monitoring and heart monitoring, smartwatches, and many more.Likewise, it’s suitable for low-power security operations and movement detection in sensitive areas.&nbsp;With a low form factor, the Infineon BGT60TR13C radar sensor can be integrated with the Infineon 60GHz radar board to create new and innovative applications for movement detection, vital sensing, and touchless interaction systems at submillimeter levels.
