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.
