摘要

地球静止干涉微波测深仪(GIMS)作为中国地球静止轨道大气观测任务中提出的微波干涉辐射计(MIR)的一个概念，预计将成为中国下一代气象卫星FY-4M的主要有效载荷。现在第二代地面验证型GIMS-II正在发展中。本文以GIMS-II的天线阵列设计为重点，旨在解决在某些特殊限制条件下天线单元位置的优化问题。最后利用差分进化算法优化了一个包含70个天线单元的圆形阵列。

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.
