- Abstract
Now casting of precipitation in geostationary orbit is strongly demanded,two of difficulties are antenna and radiometer receiver,it should satisfies both high saptial and time resolution,this paper present two satellites using 3 meters reflector with large scale feed array cofiguration get over 600 spot beams cover 3.5\% of China area in same time, work in 118GHz for atmospheric temperature vertical profile and 183GHz for humidity vertical profile, two satellites consist of interferometric synthetic aperture ,meanwhile, using high precision scan with 0.01deg. step, it can satifies weather nowcating both spatial and time resolution in suspect zone for now casting requirements.
