Design and Implementation of Automotive Anti-collision Radar Signal Processing
Linear frequency modulated continuous wave radar (LFMCW radar) is a radar system that achieves distance and velocity information of moving target by echo Doppler frequency shift.This paper provides a feasible method for automotive anti-collision radar system based on linear frequency modulation.The design realizes detection information of distance and velocity after beat frequency signal is processed by Chirp-Z Transform (CZT) algorithm,then,to improve SNR of the system by coherent integration processing.Experimental results show that the system can make real-time detection for distance and velocity of the forward target,and the system runs reliably.
