Abstract

In this work, a fast calculation method of the scattered radiance for scenario involving both the earth surface and the earth-limb regions is proposed. The single scattering equation of typical two-stream approximate is adapted to compute atmospheric radiative transfer under the spherical-parallel atmosphere assumption. With specified atmospheric profiles, spectral band and observation geometry, a two-dimensional (2-D) matrix of the scattered radiance varying with incident zenith and viewing zenith angles are then calculated. Finally, the earth disk images are generated for different spectral bands by interpolating the calculated radiance matrices. Simulation results of multispectral earth disk images for space-based earth observation sensors are presented to demonstrate the usefulness of the proposed technique for high fidelity scene generation where both the earth surface and the earth-limb regions are observed.
