Abstract	The main purpose of the paper is to propose a framework for validating radar target models using superresolution imagery methods. The need for realistic target models becomes more and more imperative as the radar technological capabilities and the signal processing techniques are continually improved. Simple scattering configurations, such as a set of well resolved scattering centers, where no geometrical visibility or secondary reflections are taken into account, are going to become completely inappropriate. A complex target model is considered in the paper, the simulated backscattered signal being obtained via the "simplest component method". The target's body is described by a set of elementary geometrical surfaces, whose reflection characteristics are known. Superposing partially scattered signals provides the global echoed signal. This way, a direct and natural link with ship's physical structure is implemented. Geometrical visibility but also interferences between components are also considered. A superresolution technique (MUSIC-2D) is then used, in order to validate the proposed model.
