One-Point Microwave Radiometer Calibration
IEEE Geoscience and Remote Sensing Letters(2020)
摘要
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. The method proves to be at least equivalent to the classical two level, as demonstrated through their intercomparison using t...
