Abstract

With the continuous development of space technology, the requirements for the technology of modeling for infrared radiation of global background are becoming higher and higher. In this paper, a novel three-dimensional model for the infrared radiation of the global background is proposed, which is rich in elements and detailed information. In the modeling, it first uses latitude and longitude for fine mesh division. Then, this model not only comprehensively consider the terrestrial, oceanic and other elements of the surface of the earth, but also consider aerosols, molecules, the clouds with various types and other elements which are in the atmosphere. In addition, the characteristics of infrared emitted and reflected radiation of these elements under different area, elevation, time and season were researched. Finally, infrared images of global background were simulated, and the results was quantitative analyzed to discuss the model precision. The experimental results show that the proposed model can truly reflect the infrared radiation characteristics of global background, which could provide basic research reference for the studies on space target detection and remote sensing data analysis, etc.
