Abstract
Aiming at the problems existing in the tracking system of mobile satellite antenna,the conical scanning mathemati?cal model and tracking performance are studied in this paper. According to the working principle of conical scanning in the tracking system of satellite-moving communication,this paper analyses the tracking characteristics of conical scanning,establishes the mathematical model of satellite signal in the tracking process,and gives the adjustment method of antenna pointing deviation from satellite in different situations. The factors affecting the tracking performance are analyzed by simulation. The results show that the better tracking performance can be obtained when the scanning angle is small,and a new alignment method is proposed. The experi?mental results show that the conical scan tracking method proposed in this paper has a short time and stable tracking performance.关键词
