蓝绿激光作为海水透射窗口，凭借其在海水中的较低损耗和自身较高调制带宽的特点，成为解决跨介质对潜通信的有效手段之一。针对星潜激光通信中大气背向散射以及海面反射效应引起水下平台位置暴露这一安全隐患问题，通过建立分层式星潜激光传输模型，仿真模拟在不同大气条件下星潜下行激光的米氏后向散射和反射效应。结合仿真结果及现有光学探测灵敏度，证明在星潜激光通信中，水下平台存在被定位的可能性，为后续装备技术发展提供参考指导。
The blue-green laser, as a seawater projection window, has become one of the effective means to solve cross-medium submarine communication by virtue of its lower loss in seawater and its own higher modulation bandwidth. This article focuses on the potential safety hazards of exposure of the position of underwater platforms caused by atmospheric backscattering and sea surface reflection effects in satellite-submarine laser communication. By establishing a layered satellite submarine laser transmission model, the Mie backscattering and reflection effects of the satellite submersible laser under different atmospheric conditions are simulated. Combining the simulation results and the existing optical detection sensitivity, it proves that the underwater platform has the possibility of being located in the satellite-submarine laser communication, providing reference guidance for the subsequent development of equipment and technology.
