某型无人机作战试验电磁环境设计方法

Design Method of Electromagnetic Environment in Operational Test

作战试验中的电磁环境效应评估是无人机性能检验的重要组成部分。面向对象的试验电磁环境构建设计评估方法,克服了传统试验方法对环境评估所存在的缺陷,利用攻击目标结构、任务飞行计划、电磁环境想定、系统效应分析模型和评估准则,可以根据评估值获取较高置信度的电磁环境适应性评价。在评估准则研究方面,依据无人机用途以及对战场电磁环境事先的认识或已有知识的掌握程度,详细探讨了与之相适应的评估准则,使无人机电磁环境效应评估更为客观和完整。

The electromagnetic environmental effects（ E3 ） evaluation of a UAV（ unmanned air vehicle） platform in operational test is ac- complished by analysis prior to actual construction and test. The evaluation approach based on Object-oriented can overcome some draw- back of conventional trial approach that is only for actual system and can not be used to evaluate the flight dynamic process. Integrating with configuration of attack target, mission programming of flight and contemplation EME （Electromagnetic Environment） , an evaluation value is used to accomplish this anallysis based on system analysis models and evaluation criteria. According to the purpose, structure character- istic and understanding of knowledge of EME, the performance criterion of equipment is modified by the state coefficient in order to accom- modate to radar twinkling interference. With these criteria, it can be ensured to evaluation of E3 for UAV objectively and completely.
