Abstract

The detection technology between trans-air and water media is a hot research issue in the world's major oceanic countries, in order to study the laser detection technology between air and underwater, this paper establishes a model of LIDAR trans-media detection of angular reflector targets in the oceanic background, and discusses the LIDAR echo power in different oceanic environments and when the target is in the seawater at different depths. The results show that the return power of the laser decreases as the depth of the target in seawater increases; when the chlorophyll background concentration in seawater increases, the return power of the laser decreases; when the wind speed on the surface increases, the return power of the laser still decreases due to the increase of the roughness of the sea surface as well as the increase of the concentration of the air bubbles in the upper layer of the ocean. The results of this study provide a basis for the use of laser technology for trans-air-water medium detection.
