Abstract

The invention discloses a method for calculating scattering characteristics of mixed suspended particles in ocean to blue-green laser, and solves the current situation that research on light scattering of the suspended particles in the ocean mostly aims at the suspended particles with single component at present. According to a real seawater background, a mixed suspended particulate matter blue-green laser scattering model closer to actual seawater is established, and the influence of the average scattering, absorption and extinction coefficients of different mixtures and the single albedo along with the change of the particle effective radius and the particle number concentration is analyzed; according to the method and the device, the influence of different mixing ratios on the average scattering phase function of the mixed suspended particulate matters along with angle change is further popularized for target detection and identification of laser in seawater and application of underwater wireless optical communication, and meanwhile, theoretical support and a new thought can be provided for experimental research on inversion of the components of the suspended particulate matters in the seawater.

Description

technical field [0001] The invention belongs to the application field of marine laser detection technology, and in particular relates to a method for calculating the scattering characteristics of blue-green laser light by mixed suspended particles in the ocean. Background technique [0002] In recent years, more and more attention has been paid to the research on the scattering characteristics of laser in seawater. Suspended particles in seawater have a significant scattering effect on blue-green laser light, which affects the transmission of underwater laser to a large extent. The scattering characteristics of suspended particles in blue-green laser light are particularly important, which is of great significance to the research fields of underwater target detection and recognition, underwater wireless optical communication, and ocean remote sensing. [0003] At present, most of the studies on light scattering of suspended particles in the ocean are conducted on suspended p...
