Emissivity Image Simulation for a High Resolution Thermal Infrared Satellite Concept

High resolution thermal infrared satellites can provide important observations for applications in various fields. For mine detection application, high resolution data can better resolve mineralogic boundaries. In this paper, an emissivity image simulation method is proposed for a high resolution thermal infrared satellite concept; and the simulated images can be used for mineral recognition and classification algorithm development using such instrument specification. Using Worldview-3 imagery as the simulation data source, the emissivity image has been generated based on a linear mixing model. In addition, accuracy analysis is conducted through comparison between simulated WorldView-3 images and the actual one. Small relative errors in every WorldView-3 band show it is feasible to use our proposed method for image simulation.
