Traffic Monitoring Object Detection and Tracking Reference Design Using mmWave Radar Sensor

TIDEP-0090

Design files

Overview

This reference design demonstrates how our single-chip millimeter-wave (mmWave) technology can be used for robust, long-range sensing in traffic monitoring and other applications. The reference design can use the IWR1642BOOST evaluation module (EVM) or the IWR1843BOOST evaluation module (EVM) and integrates a complete radar processing chain onto the IWR1642, IWR6843 or IWR8143 device. The processing chain includes the analog radar configuration, analog-to-digital converter (ADC) capture, low-level FFT processing, and high level clustering and tracking algorithms. This reference design is intended to be built on top of our mmWave SDK for a cohesive software experience including APIs, libraries and tools for evaluation, development and data visualization.

Features

Demonstration of environmentally robust object detection, clustering, and tracking using our single-ship mmWave sensor
Measurement bandwidth of up to 4 GHz
Integrated digital signal processor (DSP) to cluster objects and track their range and velocity over time
mmWave Sensor to pinpoint location of objects in 100° field of view over a range of 5 m to 180 m
Extended capability of 3D sensing using 3TX antenna on the IWR1843BOOST or IWR6843BOOST EVM
