基于雷达辐射源识别专家系统的数据融合方法研究

摘要

介绍了用专家系统进行雷达辐射源识别的方法,重点阐述了专家系统知识推理机的控制策略和推理机制,详细分析了3种数据融合方法：确定性理论方法、主观Bayes理论方法和D-S证据理论方法,并用1个实例分析了这3种方法的准确率,总结了3种方法的优缺点,对进一步研究具有借鉴意义。%This paper introduces the methods of using the expert system to recognize radar emitters, eentres on expatiating the control strategy and reasoning mechanism of knowledge reasoning library of expert system, analyzes three data fusion methods in detail： certainty theory method, subjective Bayes theory method and D- S evidence theory method, and uses an example to analyze the accura- cy of three methods, summarizes the advantages and disadvantages of three methods, which has reference meaning for the further research.
