Abstract:

Experimental data on the lidar signal amplification in a turbulent atmosphere in dependence on the structural constant of the turbulent fluctuations of the air refractive index are presented. It is established that as the refractive index structural constant increases, the amplification coefficient increases first, reaching a maximum, then decreases under the conditions of strong optical scintillations at a sounding path. The maximum of the amplification coefficient that is attainable at a given distance depends on the refractive index turbulence strength at the instant of measurement. The temporal variations in the backscatter amplification coefficient are in good agreement with the temporal changes in the magnitude of the refractive index structural constant, determined from independent measurements.

Keywords:

optical turbulence, lidar, backscattering amplification
