Single-Chip MM Radars and Applications

5 New Things to Do with a Single-Chip Radar | Line of Sight
Single-chip radar’s greatest success so far is its use for automotive safety and convenience. Some examples  are adaptive cruise control, collision mitigation with automatic braking, lane-departure sensing, and even backup object detection. And, of course, single-chip radar is absolutely essential to the success of the driverless car. So what else can you do with a single chip radar?

• 1. Drone safety.  
• 2. Automatic door openers.
• 3. Bug zapper.
• 4. Security.
• 5. Bicycle safety.

  The 3.3V BGT24MTR11 has a detection range up to 160m at 500mW power consumption and is accurate within millimeter range for near-field sensing applications. With standard VQFN package, no specialized equipment or processes are needed for production assembly and test of radar systems based on the BGT24MTRxx family
  
  • For energy efficient lighting, 24GHz Radar Systems are well-suited for adjusting the intensity level of street, industrial and office lighting by detecting moving objects or people in the designated area. 
  • The high resolution of the BGT24MTxxx family can make tank and silo level metering systems more accurate, as the system is not tricked by splashing liquid or dust. 
  • Door opening systems can also easily distinguish between someone approaching the door or a passerby. 
  • Another application is intruder alarms, where 24GHz radar can achieve room coverage area up to 270m² compared to 10m² for commonly used InfraRed (IR) systems.
  
  

• Single Chip 24 GHz Radar Transceiver - ViaSat
  The only 24 GHz fully self-contained frequency modulated continuous wave (FMCW) radar sensor on a single 5mm x 5mm chip. This highly integrated product is designed to determine the two dimensional position and velocity of multiple targets with short measurement cycles.
  Adaptability across multiple applications is achieved by controlling the transmit frequency and bandwidth through digital interface software. The frequency continually self-calibrates, making it possible to utilize the full bandwidth without exceeding emission masks even when operated over large temperature ranges.
  By using two direct-conversion receivers target position calculation is more accurate. A 250 MHz baseband bandwidth allows for measuring targets with large ranges of velocity.
