为了实现对相控阵雷达辐射源的个体识别，分析了相控阵雷达天线的方向图形成方式，提出一种基于阵元天线方向图的相控阵雷达辐射源识别技术。通过双站侦察数据得到相控阵雷达天线阵面的指向角，进而算得相控阵雷达的阵列因子函数，经过比对接收的雷达天线方向图和阵列因子函数，得到组成阵列的天线阵元方向图，最终将计算得到的天线方向图与数据库中的天线方向图进行匹配，完成对相控阵雷达辐射源的个体识别。该方法通过提取相控阵雷达天线方向图的不变个体特征，实现了对相控阵雷达辐射源的个体识别。仿真实验结果表明所提方法能够有效地对相控阵雷达辐射源进行识别。

In order to implement the individual recognition of Phased Array Radar (PAR) emittersan analysis is made to the formation of the antenna pattern of PARand a PAR emitter recognition method is proposed based on the array antenna pattern.The method calculates the heading angle of the antenna array by using the data from two ESMsand obtains the function of the array factor.By comparing the received antenna pattern with the array factor functionthe antenna element pattern of the array is obtained.By matching the calculated element pattern with the element pattern in databasethe recognition of individual PAR emitter is implemented. The method extracts the inherent characteristics of the antenna pattern of the PAR to recognize the identity of the PAR emitter.The experiments demonstrate that the method is effective.
