机载隐蔽式垂尾高频天线辐射场特性分析

内容简介：根据飞机高频天线输入阻抗的测试数据,对机载垂尾隐蔽式高频天线进行较精确的电磁建模。结合飞机复杂形体的整机电磁模型,对高频天线进行矩量法数值仿真计算,分析飞机某些关键部件位置处的天线辐射场强特性,进而确认这些关键位置处的场强强度是否超出预期设计的安全阈值。仿真结果可作为飞机电磁兼容相关方面的分析与设计的参考依据。

Abstract：According to the test data of the aircraft high frequency antenna input impedance,a more accurate electromagnetic（EM） model of the hidden high frequency airborne antenna is built.It is given a numerical simulation based on method of moment（MoM） about the composited model,which combines the high frequency antenna and the whole complex airplane electromagnetic model.In the next content,analyzed the characteristic of the antenna＇s radiation field in several key components of the airplane through the simulation result,and then confirms whether the field intensity is beyond the safety threshold value of the expected design.The simulation result is also feasible for aircraft electromagnetic compatibility（EMC） analysis and design of complex objects.
