摘要:
在分析辐射能量和温度关系的基础上,利用最小二乘法对天空温度函数进行拟合。基于菲涅尔方程,提出一种可以用于表面粗糙的地面物体辐射温度计算的数学模型。该模型适用于波长介于1~3 mm波段的计算。最后,利用3 mm直流Dicke式辐射计探测地面物体辐射温度的方式对模型进行实验验模。实验结果及误差分析表明,该模型能较好地表征粗糙表面的辐射特性,避免了复杂的电磁计算。
Abstract:
Based on the analysis on relations between radiation energy and radiation temperature,the functions of sky temperature are fit with the least square method.A radiation temperature model is introduced based on the Fresnel equation.The model can be used in the radiation temperature calculation of the ground objects with rough surfaces and is applicable to calculation in a 1~3 mm wave band.The model is verified and validated by using the ground objects radiation temperatures which are obtained by the 3mm Dicke radiometer.The verified experiment and error analysis show that the model can behave the ground objects radiation characteristic and avoid the complicated electromagnetism calculation.
