摘要
针对打击链体系中预警机雷达可靠性评估问题,通过粗糙集对原始可靠性指标体系进行预处理,采用主成分分析法,通过确定权重,将预处理后的指标约简合并,降低了评估的复杂性;提出了可靠性效能,确定了影响可靠性的主要指标,同时保持了指标的完整性;根据打击链中预警机雷达的工作流程及使用特点,在雷达可靠性效能评估模型中分析了各个指标,得到了雷达可靠性效能值;仿真验证了可靠性指标的有效性;通过分析各个指标对可靠性的影响程度,提出了基于效能的可靠性优化方法。
According to the problem of AEWR reliability evaluation in kill chain, the original reliability indexes are pre processed by rough set, using PCA to confirm the weights, the indexes are reduced and merged, which reduces the complexity in the evaluation; Relia bility evaluation is put forward, then confirm the main indexes that affect the reliability and keep the indexes~ integrality at the same time; Furthermore, the paper analyses every index in the AEWR reliability evaluation model and finally gets the value of radar reliability ; The simulation proves that the indexes are valid; At last, through analyzing how much every index influences the reliability, a rehability optimi zation method based on the effectiveness is proposed.
