灰色关联理论在辐射源识别中的应用

Application of Gray Association Theory in Emitter Recognition

针对复杂战场电磁环境中辐射源目标识别难的问题,提出了一种基于灰色关联理论的辐射源识别方法。该方法首先提取辐射源信号的特征参数,同时选取灰色关联分析中的比较数列和参考数列;其次定义辐射源数据库为识别框架并计算各传感器基本概率赋值;最后进行证据组合与决策实现目标识别。最终的应用举例及对比实验验证了该方法的有效性。

In the light of emitter recognition problem in modern complex electromagnetism signal environments,a recognition approach based on gray association theory was proposed.First,feature parameters of emitter signal was extracted,and comparing vector and reference point in gray association analysis were selected simultaneously.Second,emitter database was regard as recognition frame and basic probability assignment was calculated by gray association analysis in each sensor.In the end,evidences are combined by evidence theory from multi-sensor sources and emitter recognition was completed with decision-making.Finally,application example and contrast experiment all show that the proposed method is effective in emitter recognition.
