摘要
文章通过对雷达接收到的箔条回波信号与目标回波信号在经过小波变换分析后,得出了基于小波变换的时频分析有助于了解回波信号的特性。最后通过MATLAB计算证明了该方法的有效性。
From the time-frequency analysis for the properties of chaff-interference echoes receiving by the radar based on the wavelet transform in this paper. From this we can see the time-frequency analysis based on the wavelet transform will help us to know the properties of echoes. Simulation by Matlab results show that the method in this paper has better performance in this problerm.
