# 合成孔径声呐成像算法之CS算法仿真研究Synthetic Aperture Sonar Imaging Algorithm—The Study and Simulation of CS Algorithm

Abstract: Range Doppler algorithm is the most extensive imaging algorithm, but it has two shortcoming: Firstly, When you use a longer kernel function to improve the accuracy of distance migration, it will cause a lot of computation burden; secondly, the compression of distance is dependency for the frequency of azimuth. The CSA uses the principle of scaling proposed by Papoulis. It uses phase multiply to finish the RCMC which is changed by distance, instead of the time-domain interpolation. It also solves the dependence between the compression of distance and the frequency of azimuth.
