基于时频分布技术的雷达信号分析

Analysis of Radar Signal Based on Time-frequency Distribution Technology

分别介绍了短时傅里叶变换、小波变换、时频分布理论和信号的参数化表示等现代信号处理技术的实现原理,分析了不同理论方法的应用特点和不足,同时提供了典型雷达信号分析实例。通过对比实验,分析了信号时频分布与参数化表示方法对多分量信号处理的各自优点和局限性。

This paper separately introduces the realization theory of modern signal processing tech- nologies such as short time Fourier transform（STFT）, wavelet transform, time-frequency distribution theory and parameterized representation of signal,etc. ,analyzes the application characteristics and shortages of various theory methods,at the same time presents the radar signal analysis exampies,analyzes respective merits and localization of multi-component signal processing by signal time-frequency distribution method and parameterized representation method through comparison experiment.
