In this paper, the shortages of WVD s double-linearity in extracting the Doppler parameters of moving-targets are discussed, especially in multi-point moving-targets imaging processing based on the spectrum characteristics of moving-target echo signals in Synthetic Aperture Radar (SAR) imaging processing and the properties of WVD. Combined with the characteristics of Continuous Wavelet Transform (CWT), the responsibility and advantages of CWT in multi-point moving-target Doppler parameters extraction are analyzed. Finally a kind of multi-point moving-
target Doppler parameters extracting algorithm based on CWT are developed, and the computer stimulating results demonstrate the correctness of the algorithm.
