Equivalent testing method for shielding effectiveness of miniature unmanned aerial vehicle
微小型无人飞行器的屏蔽效能对其抗外部强电磁干扰能力有显著影响.针对微小型飞行器物理空间小、屏蔽效能难以测量的困难,提出一种基于扩比模型的等效获取方法,将原模型等比例扩大n倍得到扩比模型,利用常规屏蔽效能测试方法和测试仪器测量得到扩比模型的屏蔽效能,再根据扩比模型和原模型屏蔽效能的关系得到原模型的屏蔽效能.以巡飞弹和四旋翼无人机两种典型微小型飞行器为例进行了仿真,结果表明原模型在频率f处的屏蔽效能等于扩比模型在频率f1=f/n处的屏蔽效能,验证了该…查看全部>>
The shielding effectiveness of a miniature unmanned aerial vehicle(UAV)has a significant impact on its ability to resist strong external electromagnetic interference.An equivalent method based on a large-scale model is employed to overcome the difficulties of measurement performed inside an extremely small space.In this method,the original miniature UAV is enlarged in proportion with scaling factor n and then a large-scale model is obtained.The shieldi…查看全部>>
