摘　　要：现代雷达为了兼顾作用距离和距离分辨率,通常需要对大时宽大带宽信号进行脉压处理。文中采用两片TS201实现某机载PD雷达所需要的脉冲压缩系统。通过采用分段匹配滤波的方法,极大地节约了时间和空间。该设计满足实时性要求,具有外围电路简单、系统调试容易等优点。In order to solve the conflict of radar＇s ability to detect targets and to distinguish targets, the modern radar usually deals with the LFM signal of large time-width and bandwidth by the compression system. A design based on two DSP of TS201 which implements pulse compression of an airborne Pulse-Doppler radar is presented in this pa- per. Time and memory have been saved significantly by sending data into the matched filter successively. This design meets the real-time requirement, and has the advantages of simple peripheral circuits and easy debugging.
