摘要
本文基于船载激光通信粗跟踪很难对准的问题,采用了一种新型的基于GPS自主引导粗跟踪方法。在目标放置一GPS信号源,通过无线网络将目标位置信息传输至粗跟踪系统控制计算机。通过解算,得出跟踪系统方位轴和俯仰轴需要转动的角度(即目标值),然后精准的控制电机运转。转动的实际角度通过传感器采集,将数值传输至控制计算机,再与目标值进行作差,如此循环直到精准跟踪。通过搭建跟踪平台测控系统,并结合外场实验,得出基于GPS自主引导跟踪方法可以快速精准的跟踪目标,大幅度降低粗跟踪所需要的时间,且可以消除环境所带来的影响。
Based on the problem of rough tracking of shipborne laser communication,a new self-guided rough tracking method based on GPS is adopted in this paper.A GPS signal source is placed on the target and the target position information is transmitted to the coarse tracking system control computer through the wireless network.Through the calculation,the angle(the target value)of the position axis and the pitch axis of the tracking system is obtained,and then the motor operation is precisely controlled.The actual angle of rotation is collected by the sensor,the value is transmitted to the control computer,and then the value is different from the target value,so that the loop is accurately tracked.By setting up the tracking platform measurement and control system and combining with the field experiment,we can get a fast and accurate tracking target based on GPS autonomous guidance tracking method,greatly reduce the time required for rough tracking,and can eliminate the impact of the environment.
