Simulation for SAR Feature Image of Planar Structures

With the progress of the SAR technology, the resolution of SAR image has enhanced constantly. The characteristics of the structure is starting to look increasingly apparent. The simulating to the structures’ characteristics of SAR image can helps people access to the target information which is contained in SAR image easily in complex cases. This paper presents a simulation based on model-cutting, combined with the technique of ray-tracing to simulate the typical SAR image characteristics of target structures of the city. For example, layover, shadow, and other major features such as secondary scattering. This method can effectively simulate typical SAR image plane of the structure, and without regard to the specific physical imaging mechanism itself, is a simple and effective manner SAR image simulation methods.
