People Counting and Tracking Using mmWave Radar Sensor with Sub-1 GHz Reference Design


Design files


This reference design demonstrates the use of the IWR6843, a single-chip, mmWave radar sensor with integrated DSP, for an indoor and outdoor people-counting application along with sub-1 GHz wireless communication. This design uses MMWAVEICBOOST and IWR6843ISK evaluation modules (EVMs) together with the LAUNCHXLCC1352R1 wireless MCU LaunchPadTM. This solution is shown to localize people out to 6 meters (short range configuration) and 14 meters (long range configuration).

  • Demonstration hardware and software using the IWR6843 device and mmWave radar sensor for people counting and tracking
  • Long-range, low-power sub-1 GHz wireless connectivity using the CC1352 device
  • IEEE 802.15.4e or IEEE 802.15.4g stack with collector and sensor application
  • mmWave technology provides range, velocity, and angle information - ideal for environmental effects
  • Azimuth field of view of 120 degrees across distance of 6m, that can extend to 14m with different chirp configuration
  • Examples of implementation of static clutter and group tracking algorithms
