Abstract:

The results of the analysis of the backscattered radiation mean power enhancement in the turbulent atmosphere are presented. The above enhancement arises because of the correlation of the forward and backward waves in a random media. The analysis was performed for the strong optical scintillation regime in the turbulent atmosphere. It is shown that the laser return mean power in the turbulent atmosphere can two times exceed that in a homogeneous medium because of the correlation of the forward and backscattered waves. With the increase in the optical turbulence strength the enhancement effect decreases accordingly to the power law.
