摘　　要：为了提高伪码调相战场侦察雷达捕获目标的效率,对某新型战场侦察雷达,研究了其脉冲压缩技术;分析了工程上常用的两种时域脉冲压缩实现方法,针对该新型雷达,建立了相应的卷积器模型,对不同长度的调相码,设计了对应的系统结构并给出了改进方案,最后通过采用QuartusⅡ与MATLAB软件对脉冲压缩过程进行联合仿真分析,验证了脉冲压缩结果的正确性。This Thesis studies the pulse compression technique of a new battlefield surveillance radar in order to improve the efficiency for pseudo-random code phase modulation battlefield surveillance radar to capture objectives. Besides, this Thesis analyzes two common realization methods of time domain pulse compression in engineering, builds corresponding convolver models on the new radar, and designs corresponding system structures and puts forward improvement schemes on phase codes with different lengths. In the end, this Thesis uses Quartus Ⅱ and MATLAB software to conduct co- simulation analysis on pulse compression process and verifies the accuracy of pulse compression result.
