  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。
• At the same time , the " stop - hop - stop " approximation is no longer valid in sas due to the low speed of sound . the receiver has unavoidable movement , when echoes get to receiver from different distances . in order to overcome the problem , an image forming algorithm of multi - aperture sas is presented in the thesis , which is suitable for the case of non - " stop - hop - stop "
  为了解决测距、测速模糊问题， sas通常采用多子阵技术，而且由于sas “停?走?停”假设往往不再有效，即测绘带内不同距离回波到达基阵时，基阵存在不可忽略的运动，所以论文提出了一种“停?走?停”假设不成立条件下的多子阵合成孔径声纳逐点成像算法以得到相位保真度更高的复图像。
