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
