全谱段高光谱数据仿真数据集（2019年9月,新疆东天山地质应用试验场）

根据地物纹理特性、光谱特性得到地物反射率/发射率场景和温度场仿真数据。结合地面高程、地形因子、观测几何等进行全谱段大气辐射传输过程建模,实现大气顶层辐射亮度数据仿真。根据载荷的成像机理和设计参数开展载荷各分系统成像性能建模研究,实现全谱段高光谱数据仿真。

First, simulation data of ground object reflectance/emissivity scenes and temperature fields are generated based on the texture and spectral characteristics of ground objects. Next, full-spectrum atmospheric radiative transfer modeling is conducted by integrating ground elevation, topographic factors, observation geometry and other related parameters, enabling the simulation of top-of-atmosphere (TOA) radiance data. Finally, imaging performance modeling for each subsystem of the remote sensing payload is established according to its imaging mechanism and design parameters, thus realizing full-spectrum hyperspectral data simulation.
