基于DSP的机动车测速雷达双目标检测算法

摘要

基于频移键控(FSK)体制的机动车测速雷达,选用DSP的C6713B系列作为信号处理系统,根据多普勒原理对目标进行测速,并且利用两个载频信号的相位差信息对目标进行测距.所提算法充分利用目标的速度、距离信息,对目标进行全程识别与跟踪,实现双目标检测.%An FSK?based algorithm of speed measuring radar of motor vehicle is introduced.The C6713B series DSP is taken as the signal processing system. The speed of the target is measured according to Doppler principle,and its distance is mea?sured by means of the phase difference information of two carrier frequency signals. The speed and distance information of the tar?get are fully utilized in the algorithm to recognize and track the target in the whole process,and realize the dual?target detection.
