摘　　要：针对单个脉内特征在雷达辐射源信号(radar emitter signal,RES)识别中存在普适性差和识别性能"瓶颈"的问题,提出组合多个特征参与RES识别的方法。通过特征组合方式和识别性能的讨论分析,提出特征参数优型组合的概念,并在此基础上,研究特征参数集的构建方法。最后,根据对特征参数集的时间成本分析,提出两种典型的特征参数集——时效集和精准集,为不同需求场合的RES识别提供决策依据。To deal with disadvantages of the single intrapulse characteristic parameter used at the radar emitter signal （RES） recognition, such as bad universal application and correct rate bottleneck, a method combining several characteristics is proposed. With the work of discussing and analyzing the characteristics combination way and its recognition performance, the conception of advantage combination is defined. And based on this, the method of constructing the characteristics parameter set is researched. Finally, according to timecost analysis of the characteristics parameter set, the two typical sets, efficiency set and accuracy set, are proposed, which could supply the decisionmaking foundation to RES recognition at different situations.
