Flatness Error Evaluation of the Satellite Antenna

Tengda Liu, Chunjie Wang, and Bingjie Wang
Abstract—Synthetic aperture radar (SAR) antenna is suitable for small satellite platform. It deforms easily in unfolded state by the affection of the space thermal loads on orbit, which directly reduces the precision of the antenna. The flatness error is an important index to evaluate the thermal deformation of antenna surface. In this paper, first a new flatness error evaluation algorithm of plane in any space placement based on least square method was proposed for accurate assessment of the satellite antenna thermal deformation degree. Then the finite element model of SAR antenna for thermal deformation analysis was established and the measure points of the SAR antenna’s measure surface was picked. Finally the antenna plate flatness error was calculated based on the new evaluation algorithm and the result of analysis. The flatness error of the satellite antenna plate quantifies the degree of the satellite antenna deformation and provides the basis for further design optimization of the SAR antenna structure.

Index Terms—Flatness error evaluation, least square method, satellite antenna, thermal deformation analysis.
