摘要
通过激光威胁源情报侦察 ,可建立相应的激光威胁源数据库 ,可以从复杂、多变、快速的光电对抗环境中识别出各种激光威胁信号 .当多个威胁源同时发射激光时 ,在时间轴上形成的是杂乱无章、交错的脉冲序列 .多激光威胁源的信号分选本质上就是一个有效的去交错处理 .依据激光告警设备所能侦测的信号参数 ,对多激光威胁源情报侦察中的信号分选参数的选择及分选流程进行了讨论 ,介绍了一些多激光威胁源情报侦察中的软件分选过程中具体涉及到的相关算法 ,如预分选过程中用到的聚类算法、PRI去交错的CDIF算法及其脉冲抽取算法等 .为了说明所讨论方法的有效性 ,给出了计算机仿真结果 .
Based on the intelligence reconnaissance,the laser threat database can be established,and all kinds of laser threat signals can be distinguished from the complicated EO countermeasure envivonment.When multiple laser sources emit simultanously,the pulse sequence will be disordered and interleaved. The signal selection of multi-threat is the efficient process to eliminate the disorder. According to the signal parameters from the laser warning equipment,the way of signal selection of multi laser threat sources in the intelligence reconnaissance and the selection flow were discussed at first in the paper. The algorithm,for instance the cluster analysis used in the pre-selection,CDIF and pulse extraction etc,were presented and the simulation results were illustrated finally to demonstrate the validity.
