The digital-beam forming (DBF) SAR system utilizing a reflector antenna is a novel concept allowing better performance while being of a lower complexity level compared to the system based on a planar antenna. However the reflector based DBF SAR is still a complex system which has a number of performance parameters and characteristics influenced by the antenna design. This paper discusses a relation between reflector antenna design options and an overall performance of the DBF SAR system. As a result the performance parameters of the systems based on the considered antenna configurations are compared.
