1)radiance[英]['re?di?ns][美]['red??ns]辐射亮度
1.Study on inversion of radiometric parameters of ground objects (such as radiance and reflectivity) was little, because the band number and bandwidth of sensor restrict the application in the fields of radiometric calibration and quantification of remote sensing.以往用户对于SPOT卫星数据的应用主要针对其高空间分辨率的特性,但是因SPOT卫星传感器的波段数和波长范围有限,故利用SPOT数据进行定量遥感分析(如地物辐射亮度及反射率)的应用研究较少。
2.In this article, the 6S atmospheric model with a digital elevation model(DEM) is used to calculate direct and diffuse illumination on horizontal surface, and the illumination is then transformed to sloping surface, meanwhile, 6S model can perform atmospheric correction over the imagery and output the radiance and reflectance at the bottom of atmos.本文提出的方法中,将6S大气校正模型与数字高程模型(DEM)结合起来,计算出水平地面上接收到的直接辐射与漫射辐射,并采用一个简单公式将其转化到地形坡面上,从而实现了对地面的辐射能量校正,同时,6S模型对卫片还进行了大气改正,可输出卫片在大气层底部的辐射亮度与反射率;然后将基于坡面的反射率换算到其在水平面上的对应值,即实现了对反射率的地形影响校正。
3.A simple but accurate model of the upwelling solar radiance is of great significance for the atmospheric correction in the case of satellite remote sensing of surface parameters.发展了一个用于卫星大气订正的参数化模式 ,包括一个新的程辐射亮度模式和一个参数化的朗伯地表—大气辐射耦合引起的亮度增量模式。

辐射亮度分子式:CAS号:性质:又称辐照亮度,辐射度。符号为L。对于平行光束,它等于光源在某个给定方向上,通过或射离无限小的面积元时的辐射功率P除以与光束在给定方向的正交平面上的面积元的垂直投影面积所得之商。若光束与给定方向之间的夹角为ψ,则L=(dP/dS)/cosψ。当在所考虑的面积上辐射功率为常数时,可简化成L=P/(Scosψ)。其SI制单位为W/m2。对于在包含给定方向ψ在内的固体角dω的锥体元中行进的发射光束来说,辐射亮度为d2P/(dωdScosψ)。其SI制单位为W/(m2·sr)。
