摘要
舰船激光通信中大气对通信的信道有重要的影响.基于Kolmogorov大气湍流理论,结合舰船通信的物理条件得出了影响舰船激光通信信道的湍流的特征函数,此时的大气处在强湍流环境下;同时分析了在相应湍流强度下大气湍流对信道的影响如光束闪烁、光斑畸变等,并通过仿真对其进行了验证.
Laser communication between ships imposes great effect on communication channels when the light waves propagate in the air. Using the Kolmogorov＇s atmospheric turbulence theory, this paper derived the eigenfunction of turbulence affecting the communication channel between ships. It is proved that the atmosphere is in a strong turbulence situation at that time. The influences of turbulences with various intensities on channels were analyzed, such as light beam glimmering, facula distortion. Simulation was performed to verify the conclusion.
