摘要
叙述了天线相位中心的检测方法。改进了 GPS天线相位中心偏差的数学模型。在不考虑天线相位中心随卫星高度、方位角变化时该模型可以准确地计算出天线相位中心水平偏差大小与方向和垂直偏差的大小 ,从而提高了天线相位中心偏差的确定精度。实例表明 ,本文所提出的方法可以较准确地判断出天线相位中心水平偏差的大小与方向。
A method is provided, which is used to check and calculate the phase center bias of an antenna of GPS receiver in this paper. This method can get the bias and its direction of the phase center in an antenna of GPS receiver, which improve the reliability in checking the phase center has a bias or not. An example explains that the method in this paper can estimate exactly the bias and its direction of the phase center bias in an antenna of GPS receiver.
