Abstract: Disclosed is a vicarious radiometric calibration system. More specifically, disclosed is a ground reference target for calibrating a digital signal that is obtained through a sensor when a landmark is observed from a satellite or an airplane by using a spectral reflection factor or spectral emissivity of the ground reference target and a vicarious radiometric calibration system including the same. It is possible to derive accurate measurement results for the MWIR region by installing a ground reference target having predetermined reflectance or emissivity and having a special form on the ground with respect to the calibration of a sensor for remote exploration, such as aviation, space, and astronomy, and performing absolute radiometric calibration by using images that are obtained through the ground reference target.
