【摘要】Two-axis transportable satellite antennas (TATSAs) have been widely adopted owing to its simple structure and low cost. However, by searching in a wide range, it will take a very long searching time. Under extreme conditions, it will even fail to work. In this paper, we propose a novel roll compen-sation (RC) method for the low-cost TATSAs to achieve faster tracking even if when the antenna has no azimuth sensor. By analyzing the influence of roll axis on the system perfor-mance, details of the compensation method are derived. Simulation and measurement results indicate that the proposed RC method can ef-fectively reduce the initial searching time for satellite communication. In addition, tracking along with the ellipse path with the RC meth-od provides the highest tracking efficiency. 【总页数】12页(137-148) 【关键词】
