摘　　要：跟踪技术是低轮廓"动中通"系统的核心技术之一。研究了多板天线"动中通"系统的跟踪方案,并针对低轮廓"动中通"跟踪过程中如何获取天线指向相对于卫星方向的偏差角问题,提出了适用于一维机扫一维电扫的多板天线"动中通"系统的方位、俯仰跟踪测角算法,解决了系统的跟踪测角问题,为实现低轮廓低成本"动中通"系统提供了重要的理论参考。Tracking is one of the critical technologies in multi-planar antenna Satcom-on-the-Move （SOTM） system. The tracking scheme of multi-planar antenna SOTM was studied. In order to solve the problem of acquiring the antenna beam pointing error angle relative to the sateUite direction in the tracking of multi-planar antenna SOTM, an algorithm for azimuth and elevation angle measurement was put forward, which is applicable in the system with electronic tracking in elevation direction and mechanical tracking in azimuth direction. Thus the tracking problem of the system was solved, which supplies an important academic reference for realizing the low-profile and low-cost SOTM system.
