| 摘 要： | 雷达信号的脉内调制特征是雷达信号细微特征的重要体现,因此要对雷达信号分选和识别,高可信度地判别雷达属性,必须对雷达信号脉内调制特征进行分析。小波变换特别适用于非平稳信号的分析,作为一种特征提取的工具己得到较广泛的应用。用小波变换的方法对常见的几种雷达信号进行了调制方式的识别。

| Abstract: | The interpulse modulation characteristic of radar signals is the important embodiment of imperceptible characteristics of radar signals,so the interpulse modulation characteristics of radar signals must be analyzed if radar signals be sorted and recognized to distinguish the radar attribute with high reliability.The wavelet transform is much adaptive to the analysis of non-stable signal,and has been applied widely as a kind of tool of characteristic extraction.This paper performs the modulation mode recognition to several usual radar signals. |
