| 在分析新体制机载气象雷达系统的工作原理和基本组件的基础上，选取发射机、接收机、信号处理机和有源相控阵雷达T/R组件为首要研究对象，构建了多特征融合的气象雷达系统健康状态参数集，采用层次分析法对各状态参数合理赋权，针对新体制机载气象雷达健康状态评估问题，提出了一种基于云模型的改进模糊综合评判法，相较于传统的岭形隶属度函数，该方法通过引入云模型的概念，将模糊性和随机性纳入考量范围，从而实现了更为全面和科学的健康状态评估。 |

| Abstract: |
| Based on the analysis of the working principle and basic components of the new airborne meteorological radar system, the transmitter, receiver, signal processor and active phased array radar T/R components are selected as the primary research objects, and a multi-feature fusion weather radar system health state parameter set is constructed. The analytic hierarchy process is used to rationally assign weights to each state parameter. An improved fuzzy comprehensive evaluation method based on cloud model is proposed to evaluate the health status of airborne weather radar in a new system. Compared with the traditional ridge membership function, this method takes fuzziness and randomness into consideration by introducing the concept of cloud model, so as to achieve a more comprehensive and scientific health status assessment. |
