Abstract :
The use of sub-millimeter wave radiometer on the geostationary orbit meteorological satellite is of great significance to the study of the Earth´s atmosphere. This paper presents a single-channel quasi-optical network system around 325GHz. The diffracted Gaussian beam analysis method (DGBA) and a three dimensional visual software based on it are used. This design is used in the sub-millimeter radiometer for the study of the water molecules in the atmosphere. The simulation results achieve the desired goals, and provide the basis for atmospheric composition research.
