摘要：
This paper focuses on the estimation of the parameters of moving target of SAR. Basing on the analysis of the algorithm of Cross-correlation of azimuth power spectra which is proposed by J. R. Moreira, this paper puts forwards a new kind of algorithm in time domain. Compared with Cross-correlation algorithm, this new algorithm has the advantage of less computation loads. By computer simulation, this paper compares and analyzes these two algorithms. The estimation results in different SNR and different velocities are given. All these validate the effectiveness of this new algorithm.
