基于状态评估的相控阵雷达T/R组件维修策略研究

针对大型相控阵雷达T/R组件数量庞大、故障频发，且故障类型与多种检测参数有关的特点，提出了一种基于状态评估的T/R组件维修策略。根据T/R组件各测试数据之间的关联规则，构建了T/R组件的综合状态量和单项状态量集；针对常权重系数不能准确反映T/R组件真实工作状态的问题，引入均衡函数，并计算出了各综合状态量的变权重系数，建立了一种较为准确、客观的大型相控阵雷达T/R组件状态评估方法；根据相控阵雷达的参数指标确定了T/R组件的维修阈值，最终对机内自检检测的故障T/R组件进行状态评估，并对评分低于60分的T/R组件进行换件维修。实例计算结果表明，该评估方法和维修策略具有较高的可行性，能够充分发挥T/R组件的剩余寿命价值，对提高装备的保障效能具有重要意义。

Research on Condition-assessment-based Maintenance Strategy for T/R Module of Phased Array Radar

A condition-assessment-based maintenance strategy of T/R module is presented for the large number and frequent malfunctions of phased array radar T/R module and the fault type related to a variety of detection parameters. The synthetic and independent status parameters are established according to the association rule of each test data. In view of the fact that the constant weight coefficient can’t reflect the actual working status of T/R module accurately, a balanced function is introduced to calculate the variable weight coefficient of synthetic status parameters, an objective and accurate status assessment method of phased array radar T/R module is established, and the maintenance threshold of T/R module is determined by the tactical index of phased array radar. The proposed method is used to evaluate the fault T/R modules which are detected by built in test(BIT)，and the fault T/R modules which score is less than 60 points are replaced with the new T/R modules. The calculated results show that the assessment method and maintenance strategy have high feasibility， and make full use of the surplus value of T/R module， which are of great importance to improve the support effectiveness of equipment.
