电子战信号处理技术综述

Review on signal processing technology of electronic warfare

针对电子战(EW)的主要任务,指出电子战的核心是控制电磁频谱,包括检测、分类、识别、侦察、干扰与反干扰等主要过程都依赖于先进的信号处理技术.详细阐述了傅立叶变换、小波变换,时频分析的基本方法,分析了各自在信号处理中的优缺点,阐明周期平稳性是信号进行频谱相关性分析的基本依据.最后,给出了上述理论和方法的在电子战领域的应用及展望.

According to the main mission of electronic warfare（EW）,the view that the core of electronic warfare is being controlled of electromagnetic spectrum is proposed, and the most process of electronic warfare including test, classification, identification, reconnaissance,jamming and anti -jamming and etc all depend on advanced signal processing technology. The basic method of Fourier transform, wavelet transform and time-frequency analysis are presented in detail subsequently, advantage and disadvantage of the presented transform in signal processing are analyzed, and the fact that the cyclo-stationary is foundation for analysis of spectrum relativity is illuminated. Finally, the application and prospect of theories and methods being discussed in the filed of electronic warfare are outlined.
