Key Document
Description
This reference design demonstrates the use of the AWR6843 60GHz single-chip mmWave sensor with integrated DSP, as a Vehicle Occupant Detection (VOD) and Child Presence Detection (CPD) Sensor enabling the detection of life forms in a vehicle. This design provides a reference software processing chain which runs on the C674x DSP, enabling the generation of a heat map to detect occupants in a Field of View (FOV) of ±60 degrees.
Watch Vehicle Occupant Detection using mmWave Sensors Video.
