| 摘 要： | 研究了一种由线性调频与二相码组合而成的雷达脉冲压缩信号，给出了这类信号的表达式。文中提出了5点滑窗法线性调频旁瓣抑制滤波器，同时，针对LFM-BC雷达信号旁瓣抑制中需要进行双加权的问题，设计了一种基于5点滑窗法的旁瓣抑制加权网络。仿真实验证明，这种新的旁瓣抑制方法可以完成LFM-BC雷达信号的旁瓣抑制，同时降低了LFM-BC雷达信号脉压系统中加权滤波网络设计的复杂性。

| Abstract: | An form of radar pulse-compression signal which composed of linear frequency modulation and bi-phase coding is studied in this paper.Expression of this kind of signal is given.This paper presents 5-point sliding window LFM side lobe suppression filter,and aiming at the requirement of double weighting in side lobe suppression of LFM-BC signal,this paper designes a kind of side lobe suppression weighting net based on 5-point sliding window.By means of simulating test,it is proved that this new method could complete the side lobe suppression of LFM-BC signal and the complexity of designing weighting filter net is depressed. |
