Speckle filtering of SAR images based on sub-aperture technique and principal component analysis

In this paper, a new approach to speckle filtering of synthetic aperture radar (SAR) images is presented, in which principal component analysis (PCA) is applied to sub-aperture images for RCS reconstruction. To describe a pixel, we define a parameter vector, the covariance of which is decomposed int...
