空—地卫星光通信系统中超前对准问题的研究
The Research about Look-ahead Alignment Problem for Space-earth Satellite Laser Communication.
【摘要】 推导大气光路方程,引入物理名词蒙气差,分别计算上行链路及下行链路的偏转角,说明偏转角存在的原因并提出消除偏转角的可行性方法:通过提高发射角使其光线偏转后能精确对准.
【Abstract】 The ray refraction effect of the atmosphere was mainly studied.At first derive the equation of ray way of atmosphere in brief,then introduce the physics-noun mengqicha,calcu- late the deflection angle of the up chain and down chain respectively,and explain why the de- flection angle exist and put forward the feasible method to dispel the angle:through improve the angle of departure make light can up to the reception station of satellites just after the de- flection.
