摘要:

用计算机模拟的方法来讨论遥感像元热红外辐射的尺度效应。模拟主要针对平面非同温像元,用多变元随机量生成像元内组分不同发射率和温度,通过比较模拟的热辐射尺度效应与李小文等的Planck定律尺度纠正公式,证明该公式可正确纠正非同温像元的热辐射尺度效应。

Simulation for Thermal Emission Scale Effect of Plane Non-Isothermal Surfaces
Abstract:

In this paper we simulated thermal emission scale effect of plane non-isothermal surfaces, and validatedLi-Wang-Strahler's scale-corrected Planck law for non-isothermal surfaces; We used multivariate normal distribution togenerate component emissivity and component temperature under given the mean, variance and covariance ofcomponent emissivity and temperature. Given pixel temperature, two scale-corrected factors could be calculated.Comparing simulated scale-corrected factors with Li-Wang-Strahler's scale-corrected factors, we found the simulatedones always was close to the deduced. The simulation showed that Li-Wang-Strahler's model correctly redressed scaleeffect of non-isothermal surfaces.
