High accuracy water bath blackbody based on the information quantification of infrared remote sensing

Radiometric calibration is of critical importance for information quantification of infrared remote sensing.According to the need of infrared remote sensing,a high accuracy water bath based blackbody is developed,and the effective emssivities of blackbody are calculated using uniform specular-diffuse cavities model.The technical proposals of realizing high accurate calibration of blackbody are discussed.The experimental results show that this blackbody source can be used in the radiometric calibration of remote sensing detectors.
