基于两级证据合成的海上辐射源目标识别方法

A Method of Emitter Identification Based on Two-Stage Evidence Combination

在通用的D-S证据理论目标识别模型基础上,以海上电子侦察行动为背景,提出了一种基于两级证据合成的辐射源目标识别方法。在辐射源信号数据库和综合情报数据库的支持下,该方法分别采用灰关联法和综合分析法对辐射源信号和装备平台进行概率赋值,通过证据合成公式计算得到识别结果,实现从信号到设备、从设备到平台的两级识别目的。研究表明,该方法简单易行,有利于提高识别结果的准确性。

On the basis of universal process of target identification using the D-S evidence theo- ry, a method is propsed for identifying the emitters and targets on the sea with two-stage evi- dence combination. Supported by the database of electronic signal templates and summarized in- formation, BPAs of signals and platforms are achieved by the method of grey relation and com- prehensive analysis method, and the identification results are got through evidence theory combi- nation rule. This method is simple and feasible, and the accuracy of target identification could be improved.
