| 摘 要： | 针对目前研究较少的混合激光制导信号批次分选和码型识别问题,在分析激光制导信号编码特点的基础上,提出一种新的分选与解码算法.该算法首先采用序列差值直方图法(SDIF)识别骨架周期,然后利用已知编码规律采用变步长序列搜索法识别常规编码信号,最后根据脉冲序列独立性判断准则识别未知编码信号.仿真结果证明了该算法的有效性.

| Abstract: | A novel algorithm is proposed for the sorting and code identification of mixed laser-guided signals based on the analysis of the characteristics for encoding laser-guided signals.The algorithm follows such a sequence: firstly,recognizing possible frame cycle by sequential difference histogram;secondly,identifying conventional encoded signals by mutative step searching algorithm based on known encoding rules;thirdly,figuring out unknown codes by pulse sequences independence criterion.The effectiveness of the... |
