RESEARCH OF THE ATMOSPHERIC CORRECTION METHOD BASED ON APPROXIMATE SOLUTION OF MODTRAN TRANSMITTANCE EQUATION

Collection of selected papers of the II International Conference on Information Technology and Nanotechnology, 2016
The paper presents an experimental research of proposed method of atmospheric correction of hyperspectral remote sensing data. The method is based on approximate solution of MODTRAN transmittance equation using simultaneous analysis of remote sensing hyperspectral image and an ideal hyperspectral image of the same territory.

Rethinking the atmospheric downward longwave radiation: A black-gray body model for accurate estimation

Advances in Applied Energy
Accurately estimating atmospheric downward longwave radiation is critical for applications ranging from radiative cooling to building energy efficiency. The main challenge lies in its spectral variability, which depends strongly on sky conditions such as

紫外LED散射通信信道特性与传输研究

Guangtongxin yanjiu, 2013
利用modtran大气传输模型对低空信道紫外光传输特性进行分析,研究了近地短距离传输的大气吸收和散射的数学模型。在实验室环境下,系统采用视场角为80°的紫外LED（发光二极管）发射,在传输距离为5～8m的情况下进行了模拟信号的散射传输测试。结果表明:利用一定的有效散射体,收发俯仰角从10°增加到65°时,能有效实现短距离紫外散射传输。散射体浓度过大对紫外光存在强烈的吸收作用,传输距离将减小,单个紫外LED发射功率低,实际通信应用中,可采用阵列LED来提高发射功率,增加传输距离。
