摘　　要：针对如何高效求解装甲车辆等复杂目标的电磁散射特性的难题,利用有限元法(Finite Element Method,FEM)和物理光学(Physical Optics,PO)法对复杂装甲车辆进行3D几何建模和电磁学问题描述。通过Ansoft HFSS电磁仿真系统,对其电磁散射特性进行有限元电磁仿真求解,直观形象地解算出装甲车辆高频散射电磁场的雷达截面积(Radar Cross Section,RCS)分布状态,包括电磁波对装甲车辆不同入射面的RCS在水平、垂直方向上的电磁变化特性,为装甲车辆隐身、反隐身设计,雷达系统设计以及雷达目标识别提供数字化、信息化技术支撑。In order to effectively solve the problem of electromagnetic scattering characteristics from complex targets like armored vehicles,the Finite Element Method(FEM) is combined to construct 3D geometric model and describe electromagnetic problems in armored vehicles by the Physical Optics(PO) method.Electromagnetic simulation of electromagnetic scattering characteristics is solved by FEM through the Ansoft HFSS simulation system.In this way,Radar Cross Section(RCS) distribution of armored vehicles'high-frequency scattering electromagnetic field can be visually calculated,including the changing electromagnetic characteristics in both horizontal and vertical directions of armored vehicle RCS in different incident plane,which provides technical support of digitalization and informationization for the stealth and anti-stealth design of armored vehicles as well as radar system and radar target recognition.
