One-Point Microwave Radiometer Calibration [PDF]
IEEE Geoscience and Remote Sensing Letters, 2020 A method for internally calibrating microwave total power radiometers by using only one level of noise injection is presented. It is based on having a previous accurate characterization of the receiver noise temperature, which used de facto as a second calibration standard.
