Collision Avoidance Road-Watch Radar for Smart Highway Safety

摘要

Multi-mode Ka-band radar system has been designed and implemented for the obstacle collision avoidance on the highway. The key subsystem consists of the patch array antenna, coherent transceiver, radar signal processor, and controller. Radar signal processing algorithms include MTI and IMTI, pulse integration, CFAR, FFT， and change detection. Through the field tests using the radar data acquisition system, radar performance was analyzed in terms of detection probability of obstacles. The performance result shows 90.6％ and 10~(-6) at a distance of 500 m using the reference RCS of 30×30 cm.
