摘要
对于周期脉冲序列的信号分选识别，可采用序列搜索的时域方法[1，2]。本文将大周期内完全重复的脉冲序列分解为多个“单周期信号”．并把它们均定义为周期性信号．同时，提出了序列搜索的一种软件实现方法及密集视频脉冲信号分选的变步长、信步长快速搜索法．在此基础上，本文针对序列搜索分选法的可信度计算公式进行了推导和分析，证实了这种方法的可行性和有效性．
The sequence searching technique mqy be used to separate the periodic pulse sequence signals. This paper defines the pulse seequences which repeat completely in a large period as 'periodic signal'and decomposes them into'simple period signal'.Then, it preseents the realization of sequence searching in softwqre and the fast searching technique of changing step and duplicaring step in searating concentrated video frequency pulse signals. As for the sequence searching technique, this paper also derives and analyses the formaula of fiducial thus proves its feasibility and efficiency
