机载电子对抗系统外场可靠性持续评价方法

Continuous Evaluation Method of Outfield Reliability for Airborne Electronic Countermeasure System

针对机载电子对抗系统外场使用保障数据具有大样本、随机截尾以及数据来源多等特点,提出一种基于外场使用保障数据的电子对抗系统可靠性持续评价方法。首先,分析了机载电子对抗系统可靠性持续评价步骤;其次,给出外场使用保障数据的收集、分析与核查方法;然后,构建基于使用保障数据的设备级和系统级可靠性评估模型;最后,结合某电子对抗系统实例分析,验证所提方法的正确性。

Regarding the large amount of samples,random truncation and multiple data sources of the outfield use & support data in airborne electronic countermeasure system,a method for continuous evaluation of electronic countermeasure system reliability based on outfield use and support data is proposed.Firstly,the steps of continuous evaluation of the reliabilty of the airborne electronic countermeasure system is analyzed.Secondly,the collection,analysis and verification methods of outfield use and support are given.Then,the equipment-level and system-level reliability evaluation models based on use and support data are constructed.Finally,the correctness of the proposed method is verified via an case analysis of a certain type of electronic countermeasure system.
