摘　　要：从密集复杂的信号环境中分选和识别出特定雷达辐射源信号是信号处理领域重要内容之一。利用威胁复杂雷达信号的先验信息,引入数据挖掘领域时间序列相似性快速匹配原理及其滑窗技术,提出了一种适于多参数联合变化雷达信号快速匹配识别方法。实验表明,该方法识别速度快,适应环境能力强,具有良好的应用前景。Specific radar emitter signal sorting and recognition is the critical segment of signal process- ing from complex signal environment. With the foregone information of minatory complex signals, the principle of time series comparability in data mining field and the technique of slip window are intro- duced. So a new method of fast matching for the pulse changes of several parameters radar signal is given. With the experiments, it is showed that this method has quick recognition speed, powerful adapted environment ability and a good application foreground.
