模糊理论在雷达故障诊断中的应用研究

The Application of Fuzzy Logic in Radar Fault Diagnosis

根据模糊数学中的可能性理论引入了“故障可能性”的概念。推导了故障可能性分布的模糊数学表达式 ,并对故障可能性在串联系统模型中的分布情况进行了研究。给出了基于故障可能性分布的模糊综合评判法 ,以及根据该方法所得出的结果。论述了其如何在雷达接收机故障诊断中获取故障诊断数据 。

Based on possibility theory of fuzzy mathematics, we put forward a new conception-fault possibility and deduce it's fuzzy logic expression. According to the fault possibility distribution in a serial model system, we present a new method for system fuzzy synthetic judgement. At last, by using a serial model system for example, we discuss how to apply the result which we've got ten in this paper to acquire the relative data for fault diagnosis and fault located steps in the receiver part of a radar system.
