Paper Abstract

In order to study the atmospheric turbulence's influence on active laser reconnaissance, a theoretical model of cat-eye system illuminated by Gaussian-beam which propagates through atmospheric turbulence over a long distance was constructed. The mean irradiance and the scintillation index were calculated under the Rytov approximation. The theoretical analysis and numerical simulation results indicate that the mean irradiance and scintillation index of the active laser reconnaissance echo influenced by atmospheric turbulence are both increased near the optical axis. Experiment was carried out to validate the theoretical analysis results and the experimental results are shown to be in good agreement with the theoretical predictions.
