摘　　要：运用物理光学、几何光学、等效电流等方法对甲板、船舷和塔台等典型结构散射特性的分析,展开对舰船的电磁散射特性研究。通过对典型舰船目标电磁散射特性的仿真分析,验证电磁散射特性方法的正确性与计算可行性,给出不同方位、俯仰角目标散射特性与海面散射特性的对比分析结果,最终得出船舷可作为对舰船成像识别最佳区域的结论。The electromagnetic scattering characteristic of warship is researched in this paper. The methods such as physical optics, geometrical optics and method of equivalent current are used in analyzing the scattering characteristic of typical structures. The accuracy and feasibility is verified by simulation results of electromagnetic scattering characteristic of a typical warship target, the comparison results between the scattering properties of the target in different azimuth and pitch angle and the scattering property of sea surface are provided. Finally, the conclusion that ship board could be the best area for warship image recognition is reached.
