针对在多种不确定性因素下的雷达发射机健康状态评估问题，在综合考虑指标可测性的基础上，建立了新的雷达发射机健康状态评估指标体系。采用一种改进证据理论的多指标融合方法进行雷达健康状态评估，通过各实测数据隶属函数转化得到基本可信度分配，避免了传统方法中评估指标基本可信度函数分配的主观性和局限性，然后利用改进的D‐S证据理论对指标进行融合，实验结果验证了该方法的有效性。

For the health assessment of the radar transmitter working under the condition of various uncertain factors ,this paper presents an index evaluation model based on D‐S evidence theory and also a new index system for evaluating the health status of the radar transmitter .In order to avoid the sub‐jectivity and limitation of the basic probability function allocation ,an improved evidence theory‐based multi‐index fusion method is used for the basic reliability allocation through the membership function . Then ,the improved D‐S evidence theory is applied to the assessment fusion .The experimental results show that the proposed method is effective .
