雷达发射机健康状态评价技术研究

A Study on Health State Assessment Technology of Radar Transmitter

在分析固态雷达发射机的组成结构和工作过程的基础上,定义了描述雷达发射机健康状态的参数集。结合健康管理数据划分国际标准,给出异构参数基于劣化程度的标准化方案。建立了雷达发射机的健康评价层次结构模型,优化了层次分析法的权重关系判别矩阵构建过程,提出了改进的雷达发射机健康状态评价模糊层次分析法,利用雷达故障实际案例验证了改进方法的健康状态评价能力。

With the analysis of the structure and working process of solid-state radar transmitter, a full set of parameters to characterize the health state of radar transmitter was defined. Combined with the international criterion of health parameter, a deterioration degree based data normalization scheme for heterogeneous state parameters was given out. The layer structure for health assessment was built up, the building process of weight discriminant matrix of analytic hierarchy process was optimized and an improved fuzzy analytic hierarchy process for health assessment of radar transmitter was put forward, of which the capability of health assessment was validated by giving fault cases.
