摘要：

This article presents the scanning mechanism of push-broom satellite antenna working at 140 GHz. Such kind of antenna can be applied into many areas, such as imaging, ocean surveillance and astronomical observation. The feeds are placed at the rotary focus with a spacing of 1.72 cm between two adjacent feeds, and the center distance from the feed to the reflector surface is 14.48 cm. Meanwhile, the reflector surface is created by the rotation of a parabola with four boundaries, which is obtained by MATLAB program. Commercial software GRASP based on Physical Optics (PO) is employed to assess the performance of antenna. The simulation results of the far-field are obtained by the superposition field of each feed, which are plotted in the same output coordinate system.
