People Counting and Tracking Reference Design Using Millimeter Wave Radar Sensors

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.
