英文摘要	The quantification of remote sensing information requires spectral radiometric calibration technology support with high accuracy. This technology can ensure the comparability, accuracy and long-term stability of sensor data acquisition. Now, the calibration technique traced to the cryogenic absolute radiometer is the trend of development. In order to improve the accuracy of infrared absolute spectral response, a gold-plated hemisphere reflector is added to a thermopile detector. So an infrared trap detector is developed as the standard transfer detector. The spectral response linearity, spatial response uniformity and stability of an infrared trap detector are tested by electric substitution technology. The authors also have established an infrared radiometric calibration system based on the cryogenic absolute radiometer. The combined relative uncertainty in the spectral responsivity of this detector from 1.1 similar to 3.0 mu m is below 1%. The application of infrared trap detector to radiometric calibration can improve the calibration accuracy of sensors through its shorter calibration chain.
