摘要
在已有较为精确的CAD三维模型基础上,对典型隐身飞机目标F-22进行精细化建模和面元剖分,并利用电磁计算软件FEKO中内置的拥有较高效率和精确度的多层快速多级子算法对其进行双基RCS仿真计算。通过对仿真结果分析得出隐身飞机目标双基RCS的3个大值方向与入射方向的关系。该结论能够为双/多基预警雷达系统的设计与使用提供仿真依据。
Based on the existing CAD 3D model,the refined modeling and surface element subdivision of the typical stealth aircraft targets such as F-22 are performed,and the embedded multi-level fast multipole method(FMM)with high efficiency and accuracy in the electromagnetic calculation software FEKO is used to calculate the bistatic RCS.The relationship between the incident direction and three big value directions of the bistatic RCS of the stealth aircraft target is obtained through the analysis of the simulation results,providing the simulation basis for the design and application of the bistatic/multistatic early-warning radar system.
