Analysis of Active Interference Signal Recognition Based on Short Time Fourier Transform

阐述在对有源干扰信号建模的基础上,采用短时傅立叶变换的分析方法对干扰信号进行仿真分析。验证表明,特征分析曲线清晰,对于雷达干扰信号的脉内分析非常重要,可以作为识别雷达有源干扰信号的重要方法。

This paper describes the modeling of active interference signals and the use of shorttime Fourier transform analysis method to simulate and analyze interference signals.Verification shows that the clear feature analysis curve is crucial for intra pulse analysis of radar interference signals and can serve as an important method for identifying active radar interference signals.
