Overview

This design is a low-power and small form factor reference design based on AWRL6432, TI's singlechip 60GHz automotive radar sensor. The design uses high RF performance PCB material and is targeted for in-cabin sensing end applications like child presence detection (CPD) and intruder detection (ID). The AWRL6432 device runs machinelearning-based presence and detection algorithms to detect and classify the vehicle occupants.

Features
  • 12V automotive battery connection support
  • Small form factor design (18mm × 55mm)
  • Wide antenna FOV (120° × 120°) and 6.5dBi peak gain
