Abstract

The microwave radiometer has a series of advantages it has been applied widely in many fields [1] [2], such as romete sensing and guidance. In addition, the structure of the total power radiometer is the most simple and its sensitivity is the highest, so it is the optimum choice for airborne imaging system. Because of the influence of the gain fluctuation and other interference, the total power radiometer works unsteadily and the practical sensitivity become lower. In order to overcome these defects, periodic calibration technique is developed.
