Abstract
We describe a radiometer intended for use in the spectroradiometric complex for remote sensing of the Earth’s atmosphere. The main feature of the radiometer is application of an electrically controlled modulator-calibrator allowing one to perform measurements and thermal calibration in a wide temperature range without using matched loads and means for their connection. The principle of operation and design of the modulator-calibrator are described and the characteristics of the radiometer and its separate units are presented.
