本文在扼要地叙述了用多抽头延迟线系统组成近似的匹配滤波器来实现编码脉冲压缩的工作原理以后报导了63码元的M序列编码脉冲压缩的试验。从中可知,在实验室试样上所达到的压缩倍数比理论值差1.2分贝,压缩波形的主峯和最大边峯比与理论差8分贝。关于实验中的主要问题也作了简单的介绍。

In this paper, a brief description of the principle of multi-tap delay line approximation matched filter to achieve the principle of encoding pulse compression was reported after the 63-symbol M-sequence encoding pulse compression test. It can be seen that the compression ratio achieved in the laboratory sample is 1.2 dB worse than the theoretical value, and the main peak and the maximum edge-to-peak ratio of the compressed waveform are 8 dB worse than the theoretical one. About the main problems in the experiment also made a brief introduction.
