Tracking using radar sensors with Sub-1GHz reference design

3rd September 2018

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-1GHz wireless communication.

This reference design uses the IWR1642BOOST evaluation module (EVM) and the LAUNCHXLCC1352R1 wireless MCU LaunchPad. This solution is shown to localise people out to six metres (short range configuration) and 14 metres (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-1GHz 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 - suitable for environmental effects
  • Azimuth field of view of 120° across distance of 6m, that can extend to 14m with different chirp configuration
  • Examples of implementation of static clutter and group tracking algorithms
