Interference Characteristics of Flat Top Laser Transmission in Atmospheric Turbulent Media

In order to study the target echo interference characteristics of laser echoes in atmospheric turbulent media and obtain clear and effective interference information, this paper uses the flat-top laser to establish a statistical light intensity transmission model in atmospheric turbulent media and specifically analyzes the laser transmission distance, light spot cross-section, and turbulence intensity, respectively. The research shows that in the atmospheric turbulent medium, it is the main factor that the transmission distances of the flat-top laser effects on the light intensity, and the light intensity decreases monotonically with the increase of transmission distance. The larger the turbulence intensity is, the larger the cross-section radius of the flat-top laser is. This paper provides a theoretical basis for the construction and selection of effective interference areas.
