Abstract
This paper makes a detailed analysis on the echo signal of the repeated trajectory bistatic SAR. According to the characteristic of spotlight SAR signal, an algorithm based on Spectrum Analysis (SPECAN) method is proposed. The algorithm removes the azimuth ambiguity, and it also ensures good imaging quality over wildfield scene without defocus caused by spatial variance of target position.
