摘要:

结合某雷达项目,针对项目LFM和Taylor编码两种小时宽带宽积(TB)信号脉冲压缩效果不理想的问题,通过对两种不同小TB信号的实际回波波形和特性进行了分析,针对性地使用了倒推法和循环迭代法,获得了优化的脉压系数。试验得出结论,较之传统的匹配滤波脉冲压缩系数,采用优化脉压系数的LFM和Taylor编码小TB信号脉冲压缩主副瓣比均能提高十几dB。

关键词: 脉冲压缩, 倒推法, 循环迭代法

Abstract:

Based on a radar project,in which the result of two small TB signal (the LFM and Taylor) pulse compression methods are not good enough,the article firstly analyses the shape and characteristics of the two small TB signal.The optimum compressed coefficient is obtained by the reverse algorithm and the circulation algorithm respectively.Experiments show that the main lobe to sidelobe ratio can be improved by more than 10 dB compared with that by the traditional compression algorithms.

Key words: pulse compression;reverse algorithm;circulation algorithm
