| 摘要: |
| 雷达是一种极为复杂的军用综合电子设备，其健康状态直接关系到作战能力的可持续性，对雷达健康状态进行准确的评估，有利于真正实现雷达装备基于状态的维修保障模式。本文提出了一种基于模糊规则的雷达健康评估方法，将无法用精确数据表示的专家经验模糊化，变为雷达健康状态模糊知识库，经过模糊推理后，具有雷达健康状态智能评估的能力。文章给出了模糊控制器的结构，介绍了模糊推理的全过程，详细描述了雷达健康评估的模糊准则设计方法。最后，通过实际数据验证，该模糊准则评估方法可有效反映雷达的健康状态。 |

| Abstract: |
| Radar is a very complex military integrated electronic equipment. Its health status is directly related to the sustainability of combat capability. Accurate assessment of radar health status is conducive to the realization of condition based maintenance support mode of radar equipment. The paper puts forward a new method for fuzzy rules based health state assessment of radar. By fuzzing the expert experience which can’t express with accurate data, a health state base of fuzzy knowledge for radar is set up. After fuzzy reasoning, the system has an intelligent ability for state assessment of radar. The structure of fuzzy controller is given, the whole process of fuzzy reasoning is introduced, and the design method of fuzzy criteria for radar health assessment is described in detail. At last, the model is validated by actually measured data and can reflect radar’s health state. |
