不完备信息系统的辐射源究识别方法研

该文将粗糙集理论引入不完备信息系统下的辐射源识别。基于粗糙集理论，给出了一种新的不完备信息系统下辐射源识别模型。该方法以相似关系、相容关系作为基础，通过知识约简和决策规则的提取，较好地解决了不完备信息系统的辐射源识别问题。以雷达辐射源用途识别为例给出实例分析，说明了该模型处理不完备信息识别问题的有效性。
关 键 词 决策规则; 辐射源识别; 不完备信息系统; 粗糙集

In practical reconnaissance environment, reports with emitter parameter values take on uncertainty, illegibility and contradiction. In order to solve emitter recognition problems in incomplete information system, a new emitter recognition method based on rough set theory is presented in this paper. This recognition method does not change original information and can find decision rules directly from incomplete decision table. Examples of recognizing the radar emitter are given to demonstrate this new method. Experimental results show that this recognition method is effective.
