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.

Additional information

Reference software processing chain to detect the occupants inside a car using radar.

Additional Information
Features
  • Demonstration of mmWave sensor technology for robust detection of occupants (adults, children, pets) in a vehicle
  • Generate presence heat map with FOV of ±60 degrees
  • Source code for processing and detection based on mmWave software development kit (SDK)
  • Based on proven EVM hardware designs, enabling quick time to market and out-of-the-box demonstration
  • Radar front-end and detection configuration fully explained
