摘　　要：针对复杂电磁环境下辐射源识别处理时间长,高威胁等级辐射源不能及时发现的问题,研究了重点辐射源目标快速筛选识别技术,提出了一种脉冲样本图TOA差级识别算法,直接以重点辐射源的脉冲样本图为模板,与经过简单稀释后的全脉冲数据进行匹配,忽略重叠匹配优化后,得到重点目标识别结果,筛选识别同步完成,运算复杂度小,筛选识别速度快。数值仿真结果表明该方法在复杂电磁环境下能够快速有效地识别出重点辐射源,具有很高的工程应用价值。Aiming at the process of radiation source recognition needs along time and high threat level radiation source can not be found in time in compex electromagnetic circumstance,the fast filtration and recognition of key radiation source targets based on pulse sample figure are mainly researched in this paper and a algorithm based on pulse sample figure level of TOA difference is also proposed. The process uses the full pulse which has been simply disposed matching the pulse sample figure of the key radiation source and then outputs the key radiation source target recognition results after ignoring the overlap matching. The filtration and recognition can complete synchronously. The computational complexity is small and the speed of filtration and recognition is fast. Simulation results show that this method can recognize the key radiation source fast and efectively,and also has high engineering application value.
