基于连续小波变换的雷达信号处理

Radar Signal Processing Bud on Continuous Wavelet Transform

在步进频率雷达一维距离成像技术中，经典的傅里叶变换算法受到距离分辨率的限制，并且存在较高的副瓣电平。针对这一问题，本文提出将连续小波变换算法用于频率步进雷达的一维距离成像。该方法在保持高距离分辨率的同时，可有效降低回波信号的副瓣电平。

Based on stepped frequency radar high range resolution technique, the Fourier transform technique is limited by the range resolution and wil result in high sublobe level. In order to solve this problem, the continu ous wavelet transform is presented for stepped frequency radar range profile. The method is of high range resolu tion ability and can reduce effectively echoes' sublobe level.
