Abstract
With the development of space exploration and Earth exploration, the performance requirements for satellite antennas have increased. The millimeter wave and submillimeter wave imagers (MMSI) of Fengyun-4 meteorological satellite are highly dependent on antenna performance. To improve sensitivity and resolution, it is necessary to increase the antenna receiving area and reduce noise temperature. Large aperture reflector antennas are effective means, but they are susceptible to deformation caused by various factors, which in turn affects imaging quality. This article applies antenna parameters from Fengyun-3 satellite, simulates reflector antennas with different deformations and displacements, calculates radiation patterns using physical optics methods, and analyzes key antenna indicators, and studies the influence of antenna deformation on MMSI imaging.
