舰载光电跟踪设备目标捕获方法研究

Target Acquisition Method Study of Shipboard Photoelectric Tracker

光电跟踪设备跟踪精度高实时性好,但跟踪视场小,捕获目标难度大,并且目标在跟踪过程中不可避免被云层遮挡、浪花湮没。论文基于外引导数据提出了一种空间目标的快速捕获方法。通过分析拦截点警戒线搜索方法的原理,并给出目标长时间丢失且缺乏引导信息时的警戒线搜索流程;最后通过试验结果的分析验证方法的有效性。

Photoelectric tracker tends to be high tracking accuracy and good real-time,but its tracking field is small,its target acquisition is difficult.Moreover,during the target tracking process,target is obscured by clouds or submerged by waves.A newmethod of fast target acquisition based on real-time processing by using external guide data is proposed.Through the analysis of the theory of intercept point alert line search method,the paper putforward the alert line search process during the period of target long lost or boot message missing.Application results of real test show that the method is effective.
