机扫雷达智能BIT系统设计

Design of Intelligent BIT System for Mechanic Scan Radar

首先,给出了机扫雷达智能机内自检(BIT)系统顶层架构,介绍了系统组成和功能,引入了人工智能领域中逻辑程序作为BIT知识表示和推理的理论;然后,结合机扫雷达故障诊断例子,论述了知识表示方法和推理机制;最后,描述了系统工作过程,成功实现了基于逻辑程序的智能BIT原型系统。借助逻辑程序,系统可充分利用雷达专家丰富的经验,使BIT系统本身达到专家的水平,具备高可靠性和自动化能力。

The top level architecture of the buih-in test （BIT） system is first given, the elements and the function of the BIT system are then presented, the logic program in the field of artificial intelligence is introduced as the theory for BIT knowledge representa- tion and reasoning. And then, the knowledge representation method and reasoning schema are illustrated in details by using fault diagnosis examples of mechanic scan radar. Finally, the system workflow and the realization of the BIT system are described. With the help of logic programs, the intelligent BIT system can take full advantage of radar experts＇ rich experience, which makes the system itself achieve expert level and possess high reliability and automation capabilities.
