Abstract
Distortions in the spatial and temporal distribution of laser pulse power density introduced by the propagation medium are studied. Information about such changes is necessary in laser ranging problems, including object recognition. Based on the developed program for solving the radiation transfer equation by the method of characteristics for modeling a laser signal propagation through the atmosphere in the presence of turbulence associated with local natural and anthropogenic phenomena, the impact of these phenomena on the spatial and temporal shape of the laser pulse are revealed. Results of calculating the influence of turbulence on the temporal and spatial shapes of the signal are analyzed. Phenomena are identified in which significant distortion of a laser pulse incident on an object occurs, and it has been established that such distortions can lead to errors in object recognition in laser ranging systems.
