| 摘 要： | 针对商业电磁计算软件FEKO 具有多种数据导入接口的特点,首先利用Ansys 软件和Hypermesh 软件进行精细化建模,结合所建立的飞机模型选择合适的电磁计算方法仿真分析了典型隐身飞机目标F-22 的雷达散射截面(RCS)特性;然后,通过POSTFEKO 模块构建了目标的RCS 数据库;最后,从单基地雷达方程出发,分别从不同飞行高度、不同探测距离两个方面仿真计算了单基地雷达对隐身飞机目标F-22 的探测范围。该研究方法为建立军事目标特性数字化系统提供了理论分析和数据支撑。

| Abstract: | Commercial electromagnetic software FEKO has different leading-in interfaces of multiple data. FEKO can be used assisted by software Ansys and Hypermesh to make refined models. The model of the aircraft is established. Then, the RCS characteristics of typical stealth aircraft target F-22 are analyzed by simulation based on the computational method of electromagnetism. The RCS database of targets is built by the module of POSTFEKO. Finally, the detection coverage of monostatic radar for different height of flight and distance of detection is simulated standing on radar equation. The paper provides theoretical analysis and data for studying digital system of the characteristics of military targets. |
