Paper Abstract

The paper presents the results of an experiment on the measurements of the echo power of a coherent lidar signal from a topographic target under various turbulent conditions in the atmosphere. The intensity of optical turbulence was controlled by acoustic weather stations that registered temperature fluctuations of air near the propagation path of a probing beam. It is found that at moderate turbulence, the dynamics of the change in the recorded average power of the lidar signal echo coincides with the dynamics of the change in the intensity of optical turbulence in the atmosphere: an increase in the average power of the echo signal occurs simultaneously with an increase in the magnitude of the structure characteristic of the refractive index, and a decrease in the structure characteristic leads to a decrease in the signal ratio of the lidar noise.
