| 摘 要： | 针对干涉合成孔径声纳(InSAS)中干涉图的去噪问题,引入了一种基于偏微分方程的去噪方法.与传统的均值滤波和中值滤波方法相比较,仿真和真实试验数据处理结果均表明:基于偏微分方程的干涉图去噪方法不仅可以有效地去除噪声,而且能更好地保持干涉图的细节信息和边缘信息,为后续的相位展开奠定了基础.

| Abstract: | Aiming at the problem of interferogram denoising in Interferomatric Synthettc Aperture Sonar（InSAS）,a denoising method based on Partial Differential Equation（PDE） is introduced in this paper. Compared with the traditional average filter and the median filter, the results of the simulation and real experimental data processing show that the interferogram denoising method based on PDE can not only effectively denoise,but also better preserve the detail and edge information of the interferogram, which provides the foundation for the following phase-unwrapping. |
