Abstract :
The paper first describes the principles of remote sensing of atmospheric water vapor content and liquid water content with dual-channel millimeter wave radiometer whose central frequency is 35 GHz and 21.7 GHz respectively in detail. The block diagram and parameters of the radiometer system is given in the paper. Some experiment results measured with dual-channel millimeter wave radiometer and dual-frequency GPS receiver are given and compared at the end of the discussion.
