基于序列比对的多功能雷达搜索规律识别方法

摘要

对多功能雷达信号规律的识别是电子侦察领域的难点问题之一,本文将多功能雷达搜索方式下的工作规律表示为一个任务序列,提出了一种基于序列比对的识别方法.该方法引入了生物信息学领域的生物序列分析技术,通过将两次不同观测时间段的信号进行比对,提取其中的相似部分来达到识别多功能雷达搜索规律的目的.仿真结果证明了该方法的有效性.%Signal understanding of multifunction radars is one of the difficult issues in the field of Electronic Intelligence (ELINT) .The search schema of multifunction radars is modeled as a task sequence, and a new method is proposed based on sequence alignment which is used extensively for biological sequence analysis in the field of bioinformatics. The recognition is achieved by extracting the similarity between two observed signal intervals. Simulation results show that the method is applicable and effective.
