摘要
雷达脉冲具有时间序列的明显活动规律,传统的基于脉冲描述字的雷达脉冲频繁序列提取,只能获取脉冲序列片段,序列片段之间的时序关系不明确,无法描述整个信号的时序特征。提出了一种基于状态转移矩阵的雷达脉冲时序特征描述方法,将雷达脉冲时序分为固定序列和概率转移,通过挖掘出的雷达脉冲重复间隔序列,按照状态转移矩阵的模型,完成时序片段的拼接,描述整个雷达信号的脉冲时序特征,从而为雷达信号时序特征和工作模式研究提供依据。
The radar pulse has obvious patterns of activity of time series. Traditionally,the method of pulse sequence extraction is based on PDW,and only pulse sequence fragments can be obtained. The relationship of pulse sequence fragments is not clear,so it cannot describe the time series characteristics of the entire signal. A method of radar pulse sequences feature description based on state transferring is proposed,which divides radar pulse timing into fixed sequences and probability transfers. By excavating the radar pulse repeat interval mode,according to the model of the state transfer matrix,the local timing sequences is stitched,and the pulse timing characteristics of the entire radar signal are described. This provides a basis for the study of radar signal timing features and operating mode.
