摘　　要：针对新一代天气雷达系统构成复杂、难以定量分析系统运行状况优劣的问题,本文提出一种衡量天气雷达系统设备健康状况的综合评价方法。通过该方法建立天气雷达系统递阶层次评价体系,采用层次分析法和模糊理论进行系统运行状况的模糊综合评价,完成天气雷达系统设备及关键分机运行状况的健康指数评估,从而反映系统性能的差异和变化态势。通过雷达台站历史数据的实例分析,表明该评价方法对雷达系统的实时健康状况评估有较好的适用性,健康指数能够从整体上直观并有效反映天气雷达设备的性能差异及运行态势。To comprehensively evaluate the operational performance of the CINRAD radar system,a systematic approach for evaluating the radar system's health index was presented.This approach employs fuzzy theory and the Analytic Hierarchy Process(AHP),resulting in a hierarchically evaluation system for assessing radar equipment health index.This health evaluation method serves to evaluate the overall health of key performance parameters within the CINRAD radar,while also considering their implications for subsystems and the radar system as a whole,and to reflect differences in system performance and dynamic trends in life-cycle.Using case studies of historical data from weather radars,which shows that this evaluation method demonstrates good applicability for real-time health assessment of radar systems.
