舰船间激光通信系统视轴捕获技术

空间激光通信逐渐成为舰船间通信新型手段,但捕跟问题是舰船间激光通信最大的难点,阐述了舰船间激光通信捕获特点,分析了舰船间激光通信捕获系统的组成、工作原理和捕获策略,并着重研究捕获概率和捕获时间的影响因素,通过理论建模分析,优化捕获系统中的参数,包括捕获概率、捕获不确定区域,以及捕获时间等.结合具体使用器件对捕获系统参数进行了设计,并通过野外舰船间试验对其进行测试,实验结果测试捕获概率优于98%,不确定区域大小为26mrad,捕获时间优于30s.

Antenna Capturing Technology for Inter-shipborne Laser Communication System

Space laser communication has gradually become a new means communication between ships,but catch prob-lem is one of the largest difficulties of laser communication between ships. This paper expounds the characteristics of la-ser communication between ships captured,analyzed the composition of laser communication between ships capture sys-tem, the working principle and capture strategy, and focuses on the acquisition probability and the influence factors of capture time, through the theoretical modeling analysis and optimization of capturing the parameters in the system in-cluding the capture probability, capture the uncertain area, as well as the capture time and so on. Combined with the specific use of devices to capture system parameters for the design, and through the field test to validate its between ships, the result of the experiment test acquisition probability is better than 98%, uncertain area size 26mrad, capture time is better than that of 30s.
