Microwave Radiometer Calibration and its Error Analysis

This paper describes the meaning of radiometer calibration, the calibration methods, classification, and the comparison of the methods, classification, and the comparison of the methods, especially discusses the two-point itemized calibration equation and its error sources. It also analyses the calibration error caused by system mismatch in detail and quantitively estimates its error value. We've used above method to calibrate K and K a band radiometers.
