Abstract
Considering free-space optical communication systems, we analyze the performance of the intensity scintillation of the optical-wave propagation in the slant path under different atmospheric turbulences. Under the zero scale, we derive the log-intensity spatial covariance function of the optical-wave propagation in the slant path through the turbulent atmosphere based on the modified Rytov method. We demonstrate the relationship between the reception performance of the distributed antenna array and the aperture-averaging factor. Furthermore, we also obtain the optimum aperture diameter, number of sub-antennas, and the sub-antenna interval of the array receiver in intermediate turbulence. This study can benefit the design of the receiving system for the optical-wave propagation in the slant path through the turbulent atmosphere in free-space optical communication systems.
