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。
Aiming at the problem of how to efficiently solve the electromagnetic scattering characteristics of complex targets such as armored vehicles, 3D geometrical modeling and electromagnetics problems of the complex armored vehicle are solved by finite element method (FEM) and physical optics (PO) description. Ansoft HFSS electromagnetic simulation system is used to solve the electromagnetic scattering characteristics of the armored vehicles by finite element (EM) electromagnetic simulation. The RCS distribution of the high-frequency electromagnetic scattering field of armored vehicles is solved visually, including the distribution of electromagnetic waves to armored vehicles The characteristics of RCS in the incident plane in the horizontal and vertical directions provide digital and information technology support for the stealth, anti-stealth design, radar system design and radar target identification of armored vehicles.
