The technology of computer radar image simulation is an efficient way to solve the problem of insufficiency of radar images.The difficulty of the problem is mainly caused by the electromagnetic medeling of the objects.A new electromagnetic modeling method based on the terrain and geometry a priori information of the scene to be simulated is introduced in this paper.The validity of the simulation method is proved by simultaneous simulation of different kinds of radar imaging modes and multiparameters using the complex scene.
