无人机电磁环境效应评估及其准则研究

电磁环境效应评估是军用装备性能检验的重要组成部分。基于模型和准则的计算法评价体系，克服了传统试验方法对系统评价所存在的局限，借助计算机辅助工程(CAE)所构造的“虚拟”测试平台，利用飞机结构、任务飞行规划、预期电磁环境、系统效应分析模型和评估准则，可以以较优的费效比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、结构特点以及对预期电磁环境的认识或先验知识的掌握程度，从确定性观点和统计分析两个方面，详细探讨了与之相适应的评估准则，以期使无人机电磁环境效应评估能更为客观和完整。

Study on the Evaluation and Criteria of Electromagnetic Environment Effects for UAV

The Electromagnetic Environmental Effects (E3) evaluation of a configured military platform is accomplished by analysis prior to actual construction and test. The evaluation approach based on models and criteria can overcome some drawback 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 UAV (Unmanned Air Vehicle), mission programming of flight and contemplation EME (Electromagnetic Environment), an overall computer aided engineering (CAE) tool is used to accomplish this analysis based on system analysis models and evaluation criteria. According to the purpose, structure characteristic and understanding of knowledge of EME, two kinds of evaluation criteria are discussed, which focus on the deterministic point and statistical analysis respectively. The performance criterion of equipment is modified by the state coefficient in order to accommodate to radar twinkling interference. With these criteria, it can be ensured to evaluation of E3 for UAV objectively and completely.
