Recent mandates for automation in vehicular transportation safety have increased demand for radar applications such as forward collision detection and avoidance. The majority of current implementations of vehicular radar are mmWave radars, which are expensive and exhibit multiple security vulnerabilities. We have demonstrated the feasibility of a secure and cost-efficient IEEE 802.11-based system with radar capabilities via implementation and testing. Measurements demonstrate that our solution delivers meter level accuracy for single-target detection with just 20 MHz of spectrum provided by IEEE 802.11, supporting significant potential cost reduction of future releases of vehicular radar.
