Abstract：Sea ice plays an important role in the global climate system. In the present article, a hyperspectral radiation system for the observation of optical properties of sea ice was designed. The system consists of three optical channels, which can operate simultaneously. Two kinds of optical detectors were designed, and the problem relevant to the water-tightness was resolved. The system can be used to measure the solar radiation beneath the sea ice by an “L” bracket. Another bracket for detecting bidirectional reflectance was designed, which can fix the optical detector at any angle ranging over 0-180 measured with an angle detector. In order to make a most suitable and automatic integrated time, the system can adjust the integrated time intelligently by itself. The system can work stably under extremely low temperature. Furthermore, the system was equipped with four thermistors and one GPS. The system was validated showing a good stability and veracity in situ in the Liaodong Bay.
