针对参数相近的复杂体制雷达难以识别的问题,提出了一种基于句法模式识的雷达信号识别方法。该方法首先对已知雷达脉冲数据进行结构分析,用雷达脉冲序列参数作为句法识别中的基元进行描述,然后通过训练已知样本得出正则文法扩展生成式并构造一种多位有限态自动机作为识别器,最后选取雷达样本数据进行识别实验。理论分析和实验结果论证了该句法方法的可靠性和有效性。

Aiming at the problem of difficult radar identification caused by complex system with similar parameters,a radar identification method based on syntactic pattern recognition is presented. Firstly the structure of known radar pulse data is ana-lyzed,and the parameter of radar pulse sequences as the primitive in syntactic pattern recognition are described. Then the ex-tended regular grammar is obtained through training the known samples,and a multidigit finite automaton is constructed to be the recognizer. Finally the radar sample data is selected to have recognizing experiment. The theoretical analysis and experimen-tal results proved reliability and effectiveness of the syntax method.
