The Compound-Gaussian(CG) distribution is widely used for modeling non-Gaussian clutter,as its texture component describes the non-Gaussian properties of the clutter.In this paper,a CG model with an inverse-Gaussian texture distribution,called the Inverse-Gaussian Compound-Gaussian(IG-CG) distribution,is proposed,and its distributional properties are derived.IPIX radar lake-clutter measurements have been analyzed,and the results show that the two-parameter IG-CG distribution model fits real radar data bette...
