Abstract

The invention discloses a method for calculating the atmospheric transmissivity of a site without meteorological parameters. The method comprises the steps that position information of the site needing to be estimated is obtained; according to the position information of the site needing to be estimated and a preset searching condition, one or more sites with the meteorological parameters are found, and the found sites serve as reference sites; according to the distance between the site needing to be estimated and each reference site and the meteorological parameter of each reference site, the atmospheric transmissivity of the site needing to be estimated is obtained through calculation. By means of the method for calculating the atmospheric transmissivity of the site without the meteorological parameters, the atmospheric transmissivity of an area with unknown meteorological parameters can be calculated, and the problem about the calculation of the atmospheric transmissivity of the area without the meteorological parameters is solved.

Description

technical field [0001] The invention relates to the photoelectric characteristic research technology, in particular to a method for calculating the atmospheric transmittance of a place without meteorological parameters. Background technique [0002] When the optical signal is transmitted in the atmosphere, it will be affected by the atmosphere and cause the signal to weaken. The degree of signal weakening depends on the nature of the atmosphere on the signal transmission path, which can be expressed by the atmospheric transmittance. [0003] In the prior art, the atmospheric transmittance can be calculated by special software (for example, MODTRAN software commonly used at home and abroad), and the calculation input parameters include optical band, transmission distance length, meteorological parameters and so on. [0004] For example, let τ represent the atmospheric transmittance, but the atmospheric transmittance can be expressed as: [0005] τ=f(T,P,RH,ρ i ,λ,R) [000...
