雷达目标电磁散射的水声模拟

Underwater Acoustic Simulation of Radar Targets' Electromagnetic Scattering Characters

水声模拟是雷达目标电磁散射特性测量的具有明显优势的一种新方法。首先从电磁波和声波的波动方程出发,分析了在一定边界条件下二维目标声波与电磁波散射的对应关系;其次针对三维电大尺寸的复杂目标,分析了对其进行水声模拟测量的可行性;最后,通过对平板目标的测量实验验证了水声模拟方法的正确性。

The underwater acoustic simulation is a new method which has the obvious predominance in the measure about electromagnetic scattering characters of radar target.Firstly,according to the undulate equations of acoustic wave and electromagnetic wave,the corresponding boundary conditions about two-dimensional target were presented.Secondly,the feasibility of the underwater acoustic simulation measurement was also studied aimed at three-dimensional large electric-size complex objects.Finally,the method proposed was proved through a underwater acoustic simulation experiment with the flat target.
