摘要
提出了基于短时傅立叶变换和分数阶傅立叶变换相结合的雷达信号脉内时频分析方法。介绍了短时傅立叶变换和分数阶傅立叶变换,以及两者的联合分布,最后给出了仿真结果。
This paper proposes a method for time-frequency analysis of intra-pulse radar signal based on short time fourier transform combined with fractional fourier transform,introduces short time fourier transform（STFT）, fractional fourier transform（FrFT）, and their united distribution,finally gives the simulation results.
