摘要
对雷达系统中普遍使用的线性调频信号进行时域频域分析,介绍了线性调频信号匹配滤波器的时频特性,重点计算和分析了此类信号经匹配滤波压缩处理的过程和结果,最后对线性调频信号匹配滤波器输出过程进行建模,分析了雷达目标回波信号的接收方法以及经过匹配滤波器后的输出结果。
The linear FM signal for time- frequency commonly used in the radar system in the paper is analysed. It intro- duces characteristics of linear FM signal matched filter, focuses on compting and analyzing the process and results, which is mainly about key terms such as signal compression matched filtering. Furthermore , modeling the process of final pair of LFM output signal matched filtering. It analyses the method of radar echo signal reception and the output comes from the matched filtering in conclusion.
