The Geostationary Interferometric Microwave Sounder (GIMS): Instrument overview and recent progress

The concept of Geostationary Interferometric Microwave Sounder (GIMS) has been proposed based on the rotating circular thinned array, aiming for China's next generation geostationary meteorological satellite (FY-4M). The spaceborne system design has been investigated. The tradeoff analysis between the system performance and system complexity has been studied. A full-scale ground-based 50∼56GHz GIMS demonstrator with 28 elements has been defined and developed. Preliminary test results of the demonstrator will also be presented in this paper.
