光纤通信在舰艇水下目标追踪中的应用
|
摘要
传统水下目标追踪技术受水体传播介质环境的影响,在目标追踪效率及行进路径误差控制方面存在缺失,为此利用光纤通信在水下作业的优势,将光纤通信应用于舰艇水下标的物的定位与追踪。分析水下光纤通信的基本原理,并计算出光纤传播的角度及折射率;基于光纤通信确定出被追踪标的物的轮廓曲线函数、观测方程和动态方程,即可准确定位出标的物的基本行进路径。实验结果表明提出光纤通信追踪技术的效率优于传统的追踪技术,最优追踪路径的偏差度表现最好。
The traditional underwater target tracking technology is affected by the environment of water medium. There are some deficiencies in the efficiency of target tracking and the error control of traveling path. For this reason, using the advantages of optical fiber communication in underwater operation, optical fiber communication is applied to the positioning and tracking of underwater objects of warships. The basic principle of underwater optical fiber communication is analyzed,and the angle and refractive index of optical fiber propagation are calculated. Based on optical fiber communication, the contour curve function, observation equation and dynamic equation of the tracked object are determined, and the basic traveling path of the object can be accurately located. The experimental results show that the efficiency of the proposed optical fiber communication tracking technology is better than that of the traditional tracking technology, and the deviation degree of the optimal tracking path is the best.
