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。
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 algorithm was proved by simulation results.
