Abstract

GIMS is a synthetic aperture radiometer with 8 exploring frequencies from 50 GHz to 56 GHz. Its array is composed of 28 element antennae; 27 antennae distribute on a 2.819 m-diameter circle and one is on the center of circle. Once the array plane inclines, in-plane errors, off-plane errors and pointing errors are caused. Comparing with other two errors, the in-plane errors can be ignored. However, for the large size of the array and the pointing errors for all antennae, the effect of the inclined array plane is considerable even the inclination is as small as 0.05 degree.
