Abstract

Traditional constant false alarm rate (CFAR) detection algorithms produce a lot of false targets when applied to single-look, high-resolution, fully polarimetric synthetic aperture radar (SAR) images, due to the presence of speckle. We propose a two stage CFAR detector followed by conditional dilation to improve CFAR detection algorithms. Good results are obtained when our method is applied to single-look, high-resolution, fully polarimetric SAR images acquired from MIT Lincoln Laboratory
