Abstract

In this paper, a novel CFAR algorithm is proposed for layover and shadow detection in Interferometric synthetic aperture radar (InSAR) images. Firstly, the generalized gamma distribution (GГD) is employed for statistical modeling of the InSAR image. Moreover, a CFAR algorithm for detecting both the layover and shadow is proposed, of which the analytical expressions of two thresholds are presented. Finally, the effectiveness of the GГD and the proposed CFAR algorithm are validated with a real InSAR image.
