摘要

本文研究了合成孔径声呐(SAS)图像的预处理问题。考虑到同态滤波的特殊性，本文提出了对带有散斑的声纳图像进行同态滤波的方法。此外，还定义了鲁棒性准则来评估所提出的滤波。然后利用声呐图像的统计建模来评估滤波方法在检测步骤中的贡献。

Sonar image preprocessing method based on homomorphic filtering

This paper is concerned with the problem of preprocessing Synthetic Aperture Sonar (SAS) images. Considering its proprieties, this paper proposes to perform the homomorphic filter on the sonar images, corrupted by speckle. Moreover, robust criteria are defined to evaluate the proposed filtering. The statistic modeling of sonar image is then used to evaluate the contribution of the filtering method in the detection step.
