如何解决水下通信问题,一直是美国防部,特别是美海军最为关心的一个重要问题。为了解决这个问题,最近美国防部正在对水下激光通信的两种设想方案进行鉴定研究。两种可供选择的方案近几年来经过专家们的研究,已经提出了解决水下激光通信的两种设想方案。一种方案是在空间部署“激光反射卫星”。它的特点就是将激光器部署在地球表面的某个固定场地上,或者为了提高其生存能力,还可以把激光器装在可移动的平台上。它们产生的信号调制的激光射束 How to solve the underwater communications problem has always been an important issue that the U.S. Defense Department, especially the U.S. Navy, are most concerned about. In order to solve this problem, recently, the U.S. Department of Defense is examining two scenarios for underwater laser communications. Two options to choose from In recent years through the study of experts, has proposed two scenarios for underwater laser communications solutions. One solution is to deploy “laser-reflecting satellites” in space. Its characteristic is to dispose the laser on a certain fixed surface on the earth’s surface, or in order to improve its survivability, but also can install the laser on the movable platform. They produce a signal modulated laser beam
