Abstract

A multi-frequency microwave radiometer has been built to study the microwave remote sensing of soil, snow and vegetation cover. Its accuracy and stability has been tested. This article described the performance of its design and the performance of its components. Two absolute calibration methods and a relative calibration method and the calibration results are introduced. The theoretical and practical accuracy of the measured brightness temperature is in the range of 0.3 K-1.0 K. It is proved to be reliable and helpful in relative microwave remote sensing researches.
