SAR图像多时相组合滤波方法
Multi-temporal Combination Filtering Method of SAR Images
摘要
Abstract
An algorithm for multi-temporal Synthetic Aperture Radar(SAR) images is introduced. A linear combination of multi-temporal SAR images based on the covariance matrix is built. Weighted matrix is obtained according to the information contained in those images. With the weighted matrix, speckles in one image can be reduced with the information from other images. Three SAR images are adopted to validate the method. Experimental results show the method can achieve good speckle reduction for processing the multi-temporal SAR data simultaneously, while preserving spatial resolution of individual images.关键词
