通过分析无人机的结构层次和研究复杂电磁环境对无人机的影响,建立了复杂电磁环境下无人机的效能评估指标体系,通过主观赋权法和客观赋权法得到各项指标的权重,针对评估指标的模糊性和不确定性,基于云理论的原理,实现一定条件下评估指标的定性与定量的描述,综合考虑了评估过程中的模糊性和不确定性因素,并利用评价云模型拟合出无人机在复杂电磁环境下的综合效能。结合实例模拟分析表明,复杂电磁环境下的无人机云效能评估模型,为复杂电磁环境下无人机的定量化效能评估提供参考。

This paper analyzes the unmanned aerial vehicle(UAV) hierarchy and complex electromagnetic environment effects on UAV, and an efficiency evaluation index system of UAV in complex electromagnetic environment is established, the indexes are obtained using subjective weighting method and objective weighting method. Considering the fuzziness and uncertainty of UAV system indexes, the cloud model is used to get the combination between the qualitative and quantitative attributes of indexes, which effectively combines the fuzziness and uncertainty factors in the course of evaluation, and the total effectiveness of UAV in complex electromagnetic environment system is fitted using evaluation level cloud model. Finally, the method of effectiveness evaluation of UAV in complex electromagnetic environment is established based on cloud model, which provides a reference foundation for the quantitative efficiency evaluation of UAV in complex electromagnetic environment.
