People Counting and Tracking Reference Design Using mmWave Radar Sensor

TIDEP-01000

Design files

Overview

This reference design demonstrates the use of IWR6843, which is a single-chip mmWave radar sensor with integrated DSP for an indoor and outdoor people counting application. This reference design uses the IWR6843ISK evaluation module (EVM) and integrates a complete radar processing chain onto the IWR6843 device. This solution can detect up to 250 objects, and point and track up to 20 people with a field of view (FOV) of ±60º in the azimuth (horizontal) plane.

Features
  • Demonstration hardware and software using IWR6843 mmWave radar sensor for people counting
  • mmWave technology provides range, velocity, and angle information ideal for environmental effects
  • All detection and signal processing handled onboard the IWR6843; point cloud and object information streamed to PC for visualization
  • Azimuth field of view (FOV) of 120º across distance of 6 m (distance can be modified or extended with different chirp configurations)
  • Examples of implementation of static clutter and group tracking algorithms
