摘　　要：针对球面相控阵天线在跟踪高仰角过顶的动态目标时因方位角跳变引起的跟踪中断问题,提出了一种基于坐标系旋转的过顶跟踪方法。仿真表明,该方法很好地满足了相控阵天线角跟踪设计需要,能有效解决球面阵天线高仰角的跟踪过顶问题。目前,该方法已经成功应用于工程项目。For the problem of tracking interruption caused by azimuth angle jump when the spherical phased array antenna is tracking the dynamic target with high elevation angle zenith pass,a zenith pass tracking method based on the rotation of coordinate system is proposed. The simulation results show that this method can meet the requirements of phased array antenna angle tracking design and effectively solve the problem of spherical array antenna tracking over the top with high elevation angle. The proposed scheme has been successfully applied in engineering projects.
