“…In the same year, Smalikho made a systematic arrangement on calculating the backscattering amplification coefficient of laser radiation propagation in turbulent atmosphere by numerical simulation method [14]. In 2019, Banakh give the experimental data of lidar signal backscattering enhancement in turbulent atmosphere and its relationship with atmospheric refractive index turbulence fluctuation structure parameters through experiments, and it was concluded that the backscattering amplification coefficient would gradually increase with the increase of detection path length [15].…”
