摘要
本文分析了线性调频脉冲截断连续波 (LFMPCW)信号的处理方法 ,在传统的时间波门内DFT检测算法的基础上 ,提出了一种全新的信号处理方法—时域相关检测算法 .所提出的新算法是通过在时域对雷达回波信号进行相关处理来得到目标的距离信息 ,因而可以将雷达接收系统的补偿与信号的一维距离处理结合起来同时进行 ,在实际工程应用中更具实用性 .
Signal processing algorithm of LFMPCW signal is analyzed.Based on the traditional algorithm of DFT detection within sliding time window,a new sign al processing method,time-domain correlated detection is put forward.In the new algorithm,the range information of target is obtained from correlated processin g of radar echoes in time domain,then the range processing of signal can be acco mplished along with compensating the radar receiving system,so the new algorithm is more practicable in application.
