Abstract :
A novel NUSS-FFT(non-uniform spatial sampling FFT) SAR(synthetic aperture radar) imaging algorithm is presented in this paper. It aims at SAR imaging from non-uniform spatial sampling SAR data. Firstly, a brief analysis of SAR echo signal is presented. Secondly, the azimuth processing of NUSS SAR data is analyzed and the NUSS-FFT imaging algorithm´s procedure is presented. Thirdly, the simulation of NUSS-FFT imaging algorithm is processed. Simulation results show the effectiveness of this imaging algorithm.
