Simulation Analysis Of Aircraft-Borne Laser Communication Aero-Optics Effects

The Airborne laser communication is an important space communications development direction and also for the future of large capacity communications major way. The Airborne movement in aircraft and optical window surface formed a relatively thin turbulent boundary layer. Aero-optical effects lead to the transmission beam phase distortion effects beam quality, thus affecting capture, tracking systems and communication system performance. Impact of Airborne laser beam quality is relation to the airborne window shape, the aircraft's flight speed, altitude, optic transmission equipment parameters, such as the size of the window. But in the aviation laser communication, aero-optical effect on data-rates, tracking, bit- error rate there affected to some extent.This article reviews the development of aero-optical effects, theoretical analysis of the impact of atmospheric environment on the Airborne Laser Communication, and then the aero-optical effects on the emergence of principle, classification and engineering calculation. First under aerodynamic principles and empirical formula completed the mathematical model and then under the Airborne Laser Communication actual situation using MATLAB software computer simulation, the final paper also conducted wind tunnel aero-optical effects testing Laboratory program design.
