Scheme research on satellite and submarine blue-green laser communication initiated with submarine active mode

针对潜艇通信的现状,描述了蓝绿激光通信在大深度和高速率方面的优势,将蓝绿激光对潜通信的三种平台——飞机、临近空间和卫星平台进行了比较。从对潜通信军事需求和现实可行性出发,首次提出基于低轨道卫星的双向星潜通信方案,对潜艇主动取报的通信方案进行了详细描述,利用STK软件对典型的低轨道卫星对潜通信的覆盖区域和通信时间进行了仿真。结果表明,基于低轨道卫星的蓝绿激光星潜双向通信是完全可行的,这是现阶段实现蓝绿激光星潜通信的最优方案。

Compared with wireless radio means, the characteristics of blue-green laser submarine communica- tion are summarized, and the special advantages of big depth and high rate are emphasized. Three typical communication platforms and corresponding communication mechanisms based on the aircrafts, near-space platforms and the satellites are compared. Considering the military requirement and practical feasibility, a scheme of submarine laser communication adopting LEO satellites is put forward, and the detailed communication plans initiated by submarine are described in detail. Then the simulation of communication coverage and time for a typical LEO satellite is performed with STK software. Results show that the two-way blue-green laser communication between LEO satellite and submarine can be realized and it is the optimal feasible scheme at present.
