摘　　要：为解决传统的偏微分方程滤波方法中高斯预滤波会损失细节的问题,提出了一种基于耦合偏微分方程的干涉合成孔径声纳(InSAS)干涉图滤波方法。在滤波过程中,通过引入边缘强度函数来控制图像边缘处的滤波强度,以达到保护边缘细节的目的。通过仿真实验和真实InSAS干涉图滤波处理实验,将该方法的结果与传统的偏微分方程方法结果进行比较,验证了该方法在去噪能力和保持边缘能力方面的优越性。Aiming to solve the problem that gauss prefiltering lose details in traditional partial differential equation filtering method,this paper proposed an interferogram filtering method for interferometric synthetic aperture sonar(InSAS)based on coupled partial differential equation.In the filtering process,the edge intensity function is introduced to control the image edge to keep the consistency with the original image edge as far as possible,so as to protect the edge details.Through the simulation experiment and the real InSAS interferogram filter experiment,comparing the result of the proposed method with traditional PDE method,the superiority of the proposed method is verified in the ability of denoising and edge preservin.
