摘要
针对海基激光通信系统中存在的光束跟踪精度不足及其稳定性差的问题,文中提出了一种基于光束稳定控制的海基激光通信ATP技术,其结合船舶平台姿态预补偿与增强型NGO算法优化的BiLSTM模型,实现了高精度的光束跟踪与稳定控制。在该技术方案中,船舶平台的姿态变化会实时通过预补偿模块进行检测与修正,从而有效抵消船舶运动对光束方向的干扰。同时,增强型NGO算法优化的BiLSTM模型能够基于历史跟踪数据和环境变化预测光束偏移趋势,提前调整指向,显著提高了跟踪精度与响应速度。通过仿真与实验验证,所提方案在标准海况环境下的跟踪精度约为14μrad,有效提高了激光通信系统的稳定性和跟踪精度。
Aiming at the problem of insufficient beam tracking accuracy and stability in the sea based laser communication system,an ATP technology is proposed for sea⁃based laser communication based on beam stability control,which combines the ship platform attitude pre⁃compensation and the BilSTM model optimized by the enhanced Northern Goshawk Optimization(NGO)algorithm to achieve high⁃precision beam tracking and stability control.In this technical scheme,the attitude change of the ship platform will be detected and corrected through the pre compensation module in real time,so as to effectively offset the interference of ship movement on the beam direction.At the same time,the BiLSTM model optimized by the enhanced NGO algorithm can predict the beam deviation trend based on historical tracking data and environmental changes,adjust the direction in advance,and significantly improve the tracking accuracy and response speed.Through simulation and experimental verification,the tracking accuracy of the proposed scheme is about 14μrad under standard sea conditions,which effectively improves the stability and tracking accuracy of the laser communication system.
