Key Radar Emitter Fast Recognition Based on Set Pair Analysis and Slip Window Technology

在现代密集信号流中,快速识别出重点目标能为战场准备赢取宝贵的时间,并为战场提供决策依据。针对重点雷达辐射源的快速识别,提出了一种基于SPA和滑窗技术的重点雷达辐射源快速识别技术。该方法直接以经过简单预处理的全脉冲与重点雷达辐射源脉冲样本图匹配,无需传统方法的分选和特征提取过程,通过集对分析中的联系度判断脉冲对是否匹配,引入滑窗技术,缩短了处理时间。仿真表明,该方法识别准确率较高且识别速度快,具有较好的应用前景。

In the modern dense signal flow, to rapidly identify the key target can win precious time and provides basis for decision making in the battlefield. In order to rapidly identify the key radar emit- ter, a method based on set pair analysis（SPA） and slip window technology is proposed, which directly u- ses the full pulse which has been simply disposed with the pulse sequence pattern（PSP） of the key radar emitter to matching and does not need a process of deinterleaving and feature extraction as the convention- al method. The matching rule of the pulse is determined by the degree of connection of SPA, and the slip window technique is used in this method, so the processing time is reduced. Simulation results show that, this method has a high accuracy, fast recognition speed and a good application foreground.
