基于环境适应性的无人机电磁仿真研究

电磁环境的日益恶化使得无人机面临着前所未有的威胁。本文通过分析可能遭遇的电磁信号，结合战场电磁环境数据库和任务飞行规划，对基于环境适应性的无人机电磁半实物仿真技术进行了研究，并依据外界电磁环境对无人机的威胁途径，在一定程度上可归结为天线端口和机载电缆，提出了天线端口注入和机载电缆注入的电磁环境仿真方法，从而克服了传统全实物仿真中无法动态仿真电磁环境的弊端，降低了对仿真试验设备和场地的要求。

Research on Electromagnetic Simulation for UAV Focused on Environment Applicability

UAV (Unmanned Air Vehicle) is confronted with the tremendous threaten along with depravation of EME (Electromagnetic Environment) increasingly. Unfortunately, in the open literature, it is failing to find detailed information about Electromagnetic Simulation for UAV. On condition of analyzing the electromagnetic signal encountered by UAV, an electromagnetic simulation technique of half-practicality is studied, which is combined with electromagnetic environment database, mission programming in flight and focused on environment applicability. Some available electromagnetic simulation methods, i.e. antenna-port-injection and conducted injection, are put forward in accordance with the reality that antenna-ports and airborne-cables are feeble to electromagnetic threaten in UAV. These methods reduce the demand to simulation equipment and test site, and overcome the drawback that the various dynamical electromagnetic threaten in flight could not be simulated in full practicality system.
