| 摘 要： | 传统CINRAD/SA雷达运行状态评估方法主要依靠雷达的平均无故障时间,未考虑雷达各组成部件对雷达整机正常运行的影响权重。此外,单纯依靠分值评价也不便于对雷达的运行维护工作进行评价。该文通过对雷达部件进行层次划分,给出不同部件对于雷达正常运行影响的权重,进而计算雷达运行状态分值,在运行状态分值的基础上,通过隶属度函数,计算等级评价结果与隶属度。在全国范围内选择了8部CINRAD/SA的历史故障数据进行了验证,结果表明评价结果与雷达的实际运行保障情况是相符的。

| Abstract: | The method of Mean Time Between Failures (MTBF) is used commonly to evaluate the status of CINRAD/SA radar operation, which ignores the fact that different parts have different influences on the operation status of radar. However, only numerical degrees cannot reflect the quality of maintenance work. A new method is proposed, in which CINRAD/SA radar is divided into parts according to the radar structure, and after each part is given a weight on the basis of its influence on the operation of radar, the ranking of radar operation and its grade of membership are computed by means of membership function. Simulation using the operation logs of 8 CINRAD/SA radar shows that the algorithm is more accurate and effective than MTBF approach. |
