Abstract

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 space borne 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.
