Abstract

The invention belongs to the field of optical communication technology and atmospheric environment science, and realtes to an ultraviolet light scattering simulation method based on discrete cumulative summation. The ultraviolet light scattering simulation method based on discrete cumulative summation comprises the steps that the lower limit of the radius of atmospheric aerosol particles is 0.001micron, the upper limit of the radius of the atmospheric aerosol particles is 20 microns, the interval is 0.001 micron, cumulative summation is conducted on light scattering of all the particles, anda Monte Carlo method is improved based on discrete cumulative summation; the method comprises a Mie scattering method, a discrete accumulation summation method and a multiple scattering channel model.The multi-scattering channel model judges the scattering type and determines the scattering type of ultraviolet photons, and if aerosol scattering occurs, the Mie scattering theory is met, and a discrete accumulation summation method is used for calculating a light scattering coefficient; and discrete cumulative summation is carried out to obtain scattering, absorption and extinction factors of the polydisperse aerosol model on solar blind ultraviolet light. A discrete cumulative summation method is combined, a method for solving atmospheric scattering, absorption and extinction coefficientsin a Monte Carlo method is improved, and the precision of the simulation method is improved.

Description

technical field [0001] The invention belongs to optical communication technology and atmospheric environment science, in particular to an ultraviolet light scattering simulation method based on discrete cumulative summation, and also relates to the integrated innovation of ultraviolet light communication technology and atmospheric environmental science. Background technique [0002] Aerosol particles not only play a vital role in climate change and air pollution, but changes in their physical and chemical properties will have a certain impact on light transmittance and light scattering characteristics. [0003] Ultraviolet light with a wavelength of 200-280nm is called "sun-blind" ultraviolet light. "Sun-blind" ultraviolet light uses the scattering of aerosol particles to realize non-direct-sight communication, which can make up for the lack of alignment of laser communication, and is suitable for complex environments and In scenarios such as strong electromagnetic interfere...
