Antenna array optimization for the new GIMS demonstrator

The Geostationary interferometric microwave Sounder (GIMS) as a concept of microwave interferometric radiometer (MIR) proposed for China's geostationary earth orbit (GEO) atmosphere observation mission is anticipated to be the main payload of the China next generation meteorological satellite FY-4M. Now the second generation of ground demonstrator GIMS-II is under development. This paper is focused on the antenna array design of the GIMS-II and intended to solve the optimization problem of the antenna elements locations under some special limitations. Finally an optimized circular array with 70 antenna elements is achieved by using the differential evolution (DE) algorithm.
