Abstract
The energy attenuation, fluctuations of arrival angle, light intensity scintillation, beam drift and beam spreading, which are caused by atmospheric attenuation and turbulence, will severely degrade the performance of space laser communication systems. For evaluating the laser transmission characteristics in atmosphere in Beijing, a measurement system is designed and implemented, which includes signal data acquisition unit, data processing unit data transmission unit. With this measurement system, the atmospheric parameters were measured at specific time period in one day as well as different typical climatic conditions, which lasted up to one year, and a lot of measurement data were acquired. Through a detailed analysis to these data, the laser transmission characteristics in atmosphere in Beijing are evaluated comprehensively, which supply a reference background for the real application of space laser communication technology in Beijing.
