millimeter waves radiation temperature modeling rough surfaces detection
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.
