Research on end-to-end thermal infrared remote sensing image simulation algorithms

Simulation of remote sensing imaging plays an important role in the pre-evaluation of sensors and the development of remote sensing models. With the rapid development in thermal remote sensing observation, the simulation of thermal remote sensing imaging has been more and more important. This paper presented an end-to-end thermal remote sensing image simulation algorithm, brought together the simulation of land surface radiance scene, atmosphere radiance transfer and sensor, realized the space-borne push type thermal infrared remote sensing image simulation, and developed a thermal remote sensing image simulation system. By evaluating the geometric and radiant characteristics of the simulated remote sensing image, the result shows that this algorithm is useful to support the evaluation of the characteristics of thermal sensors and the research of pre-research algorithm.
