Description

This reference design demonstrates the use of the IWR1642, a single-chip, mmWave radar sensor from TI with integrated DSP, for an indoor and outdoor people-counting application along with Sub-1 GHz wireless communication. This reference design uses the IWR1642BOOST evaluation module (EVM) and the LAUNCHXLCC1352R1 wireless MCU LaunchPad™. This solution is shown to localize people out to 6 meters (short range configuration) and 14 meters (long range configuration).

Features
  • Demonstration hardware and software using the IWR1642 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
