摘　　要：大型深空测控天线内部采用波束波导进行微波信号传输,来波信号经过主副反射面以及各种反射镜反射后进入馈源网络,馈源网络的电轴和天线的机械轴之间存在相对运动,通过对这种方式目标跟踪误差形成机理的分析,给出目标跟踪误差的校正方法,实现大型深空测控天线对深空目标的自动跟踪。Beam waveguides are used for microwave signal transmission in large-scale deep space measurement and control antennas.Incoming wave signals are reflected through the main and secondary reflector and various mirrors into the feed network.There is a relative motion between the electrical axis of the feed network and the mechanical axis of the antenna.By analyzing the mechanism of target tracking error,The correction method of target tracking error can be used to realize the automatic tracking of deep space target by large-scale deep space measurement and control antenna.
