Abstract


In the dissertation, the radiation characteristics of the earth-atmosphere background have been studied. First of all, the process of radiative transfer in the atmosphere has been theoretically reviewed. Secondly, according to the radiation characteristics of the earth-atmosphere background, an approximate algorithm has been established, which is of significance in remote sensing. The main research work and results included in this dissertation were listed as follows.1、The process of deducing the RTE(Radiative Transfer Equation) from theory of particles transport and the approximation methods be used to solve the RTE have been discussed. The RTE have been solved by single scattering revised andδ-fit, which is a fast algorithm in remote sensing.2、The databases and the methods for calculating important parameters in RTE, including optical thickness, phase function and single-scattering albedo, have been completely analyzed. Because the atmosphere parameters from the surface of earth to the top of atmosphere vary nonlinearly with height, the atmosphere have been divided into 32 layers. The transmittance of molecular in atmosphere has been calculated by MODTRAN software, and a transmittance database with the spectral resolution of 1nm has been established. The optical parameters of aerosol including optical thickness, phase function and single-scattering albedo, have been calculated with the Mie theory.3、A model for calculate the radiative intensity has been established according to the radiation characteristics of the earth-atmosphere background. Based on VC++, a software for analyzing the radiative intensity of earth-atmosphere background has been developed. The software can be used to calculate radiative intensity at given climate condition, including the visible distance, relative humidity, wind speed and different surface albedo, and different geometric condition including the solar direction(zenith and azimuth) and observed direction(zenith and azimuth).
