摘要
脉内特征分析是雷达信号分选的基础,也是电子对抗领域里的一个重要课题。主要讨论了用小波变换结合傅立叶变换的谱分析来识别雷达信号的脉内调制特征,并给出了仿真结果。
The intra-pulse characteristic analysis is the foundation of radar signal sorting and is also an important topic in electronic countermeasure domain. This paper mainly discusses how to identify the intra-pulse modulation characteristic of radar signal by means of the spectrum analysis combining wavelet transformation with Fourier transformation,and gives out the simulation result.
