The thesis involves all - aspect of the signal processing of interferometric synthetic aperture sonar , especially in the challenging problems such as phase - preserved sas imaging algorithm , image registration , interferogram denoising filtering and two - dimensional phase unwrapping . in allusion to difficulties and emphases , some new methods are proposed . the study is important to prompt the development of interferometric synthetic aperture sonar in china
本论文对干涉合成孔径声纳信号处理过程进行了全面的论述，对其中的关键技术如保相的二维成像算法、复图像配准、干涉图降噪滤波和二维相位展开作了重点分析，并提出了一些新的方法，论文对推动我国干涉合成孔径声纳信号处理技术的研究具有重要的意义。
The author discusses the phase - preserved sas imaging algorithm , which is the precondition of interferometric processing . several classical sar algorithms used in sas are analyzed . because of the contradiction of the unambiguous range and along - track sampling requirements , multi - aperture technique is widely used in sas
探讨了保相的sas成像算法，它是后续干涉处理的前提，分析几种常用的合成孔径雷达( sar )成像算法在sas中的应用，通过理论和实验比较各自优缺点。
