Abstract This paper presents the basic concept of Extended Wavelet Transform (EWT) algorithm based on Extended WVD (EWVD) transform theory after analyzing the spectrum characteristics of airborne SAR moving-target backscatters, and then takes a comparison and analysis on airborne SAR moving-target Doppler parameters estimation by EWVD and EWT methods respectively. The flexibility and advantage of airborne SAR moving-target Doppler parameters estimation based on EWT method are indicated and the simulating experimental results demonstrate the accuracy of our conclusion.

Key words： Airborne SAR Moving-targets Doppler parameters estimation EWVD EWT
