针对基于五大常规参数的传统雷达辐射源识别方法的局限性,提出关于方位角稀释后的脉冲串波形数据的雷达辐射源自动识别方法.该方法通过对脉冲串波形数据的波形调理与脉冲分离、脉内特征参数提取、信号调制类型识别、脉冲归类和所属雷达辐射源识别等环节的设计研究,完成雷达辐射源自动识别系统架构的工程实现.采用模拟数据测试结果表明,基于该方法设计的系统识别速度快、准确率高,可为雷达对抗侦察设备的改进提供重要参考.

Aiming at the limitation of the traditional radar emitter identification method based on five traditional parameters,this paper proposes an automatic identification method of radar emitter for pulse train waveform data diluted by azimuth angle.Through designing and studying the pulse train waveform data’s pulse preprocessing and separation,extraction of intra-pulse characteristic parameters,identification of signal modulation type,classification of pulse and identification of radar emitter,this method accomplishes the engineering realization of the architecture of radar emitter automatic identification system.The test results of simulated data show that the system designed based on the proposed method has fast identification speed and high identification accuracy,which provides an important reference for the improvement of radar electronic warfare reconnaissance equipment.
