In this project, multi-static SAR systems are analyzed. Here, it is important to find the correct balance between the existence of a solution and the uniqueness of the same solution, ie to find a simple and accurate scattering model that can be used to model the interaction between the considered objects and the used electromagnetic fields. The traditional SAR model is based on an ideal point scatterer. This model is very successful for high frequency systems with a moderate aperture angle. For low-frequency systems with a large aperture angle or multi-static operation it is also observed that the point scatter model is less satisfying. In this project it is shown that a simple anisotropic scattering model based on dipole scattering can be used for these systems.
