摘　　要：为了缩短某类伪码调相正弦调频连续波雷达的探测时间,增加目标的自动识别功能,同时减少其接收单元的体积,用数字信号处理芯片代替了原来的模拟接收部分,并用一路卷积的算法代替了原来的多路相关。后期通过试验证明了此数字化接收系统的探测时间比原系统的接收时间缩短了50 ms,最高的目标识别率达到了75%,能满足实际应用的需求。To reduce the detecting time of some PRC- CW radar, bring in the ability to recognise targets automatically, DSP is used to displace the Original analog parts. Besides,once- convolution algorithm displaces correlations. Finally, by many experiments,it is proved that the detecting time is reduced by 50ms, and the best targets realization rate is 75 %, all of which can meet the actual need in practice.
