For pre-launch field radiometric calibration for the visible channel of scanning radiometer of satellite FY-2-05,the traditional radiation calibration method has been adopted,on the other hand,a novel method called Detector Based Reflectance Calibration(DBRC) which is independent of spectral response function of scanning radiometer has been advanced.
为了对FY-2号05星扫描辐射计可见光通道进行发射前外场辐射定标,在采用了传统的辐亮度定标方法的同时,提出了一种新型的独立于扫描辐射计可见光通道光谱响应函数的基于标准探测器的反射比定标法(Detector Based Reflectance Calibration)。
The emissivity ε of the honeycomb blackbody is measured for radiation calibration of the radiant cooler in the FY-1 Meteorological Satellite and the measurement results agree well with the calculated ones with Gouffe's formula.
In chapter 4, the integrating sphere calibration technique is employed to eliminate the influence of diffuser's BRDF measurement. The radiance calibration uncertainty is reduced from 4.6% previously to 2.8% currently;
Based on the mechanism of radiance calibration,the reason of gray fluctuates for ocean thermal image is analyzed. According to the character of ocean thermal image data,the wavelet transform is suggested to smoothly filter the thermal image,and the result is good.
An overview of MODIS radiometric calibration and characterization
The radiometric calibration required for precise operation and testing does not yet exist, but the imminence of important applications justifies parallel, rather than serial, development of radarclinometry and radiometrically calibrated radar.
The trends in sensitivities support the use of the radiometric calibration of Del Zanna et al.
Spectral characteristics of a spherical radiometer and its role in radiometric calibration of optoelectronic radiating elements
The influence of the form of the spectral sensitivity function of spherical radiometers on the error of radiometric calibration of optoelectronic radiating elements is demonstrated.
