标题： Direct measurement of laser aberration and ahead point from ARTEMIS satellite through strong clouds

摘要： 激光通信相比射频通信有所进步，这是由于从紫外线到近红外的载波频率非常高。 可以形成非常高的功率密度的非常窄的激光束。 但是激光束在云层、湍流、气溶胶和大气分子的散射上具有高破坏性和衰减性。 低地球轨道（LEO）、中地球轨道（MEO）和部分静止地球轨道（GSO）卫星在天空中移动，来自卫星的激光光穿过大气的不同湍流条件、云层、大气分子H2O、O2、N2、CO、O3等。 我们进行了独特的实验，通过ARTEMIS卫星的OPALE终端信标传播激光束穿过薄云。 我们发现，有一小部分激光辐射是从卫星之后的时间传播后卫星将到达的点接收的。 这与相对论中光的像差理论一致，即在从运动坐标系到非运动坐标系的转换过程中。 这对于通过大气和云层的激光通信是积极影响，因为可以开发一种系统，在从地面到卫星的激光通信期间减少大气湍流。 感兴趣的是，当激光辐射从卫星穿过强云时会发生什么。 本文详细描述了通过强云的ARTEMIS GSO卫星激光实验以及通过强云的激光功率估算。 因此，我们必须寻找最佳波长和激光功率，以在不同多云条件下进行激光通信。 显示英文摘要

摘要： Laser communication has advances in compared with radio frequency communication as result of much high carrier frequency from ultraviolet to near infrared. Very narrow laser beam is possible to form with very high power density. But laser beam has high destruction and attenuation on clouds, turbulence, scattering on aerosols and molecules of the atmosphere. Low Earth orbits (LEO), Middling Earth orbits (MEO) and partly Geosynchronous Earth orbit (GSO) satellites moving on the sky and laser light from satellites moves across different turbulence conditions of the atmosphere, clouds, molecules of the atmosphere H2O, O2, N2, CO, O3 and other. We performed unique experiments with propagation of laser beams from beacon of OPALE terminal of ARTEMIS satellite through thin clouds. We have found that small part of laser radiation is received from ahead point there the satellite will be after time of propagation of laser radiation from the satellite to telescope. It is in accordance with theory of relativity for aberration of light during transition from moving to not moving coordinate systems. It is positive effect for laser communication through the atmosphere and clouds because will be possible to develop a system for reduce of the atmosphere turbulence during of laser communication from ground to the satellites. The interest is what will be during propagation of laser radiation from the satellite through strong clouds. The detail descriptions of laser experiment with ARTEMIS GSO satellite through strong clouds and estimations of the laser power through strong clouds are presented in this paper. Accordingly we must search the optimal wave lengths and power of lasers for performs laser communication in different cloudy conditions.
