Distributed Targets Modelling using Canonical shapes in Synthetic Aperture Radar Systems

In this paper, in order to simplify calculation of the distributed target response, a new model of distributed targets is presented using monostatic SAR (Synthetic Aperture Radar) imagery. Distributed targets are strategic, because they are important in various fields, especially in military. Calculating the response of these targets is difficult due to the complexity of modelling and scattering data calculation. We solve this problem with replacing the scattered pixels with canonical shapes. Besides the simplicity, this model gives the response close to the real model. This model facilitates the target detection, target design, scattering data analysis, and distributed targets interpretation of radar viewing. In fact, one of the goals of this paper is to predict the scattering data of a scene. For this purpose, the scattering field of a real model is calculated and compared with the proposed model.
