Abstract
Beijing Institute of Satellite Environment Engineering has been engaged in the radiometric calibration of satellite remote sensor since 1980s. Recently, one calibration test for the multi-spectral scanner of CBERS-1 resource satellite has just been completed. This test was performed in the KM6 calibration facility, which is the latest one designed for radiometric calibration of satellite infrared sensor in the auxiliary chamber of KM6 environment simulator. In this test, a set of multi-spectral sources were used, which include a solar integrating sphere whose spectrum covers the visible light and near infrared, and a blackbody whose spectrum covers the far infrared. For performing the multi-spectral radiometric calibration in one test, the multi-spectral optical system was used. By controlling the precision mechanism in the vacuum cryogenic environment, the multi-spectral optical system can be switched, and the light from integrating sphere or blackbody can be individually reflected to the scanner. This paper mainly describes some technologies of the multi-spectral sources, the multi-spectral optical system and etc in this test.
