建立了天线安装非理想情况下的坐标变换模型，详细分析了由此而引入的系统测向误差，文末提出了一种补偿方法，它可以使天线安装的要求大大降低。

This paper constructs the model of coordinate transform about antenna setting error. Angle measurement error is analyzed in detail. A compensation approach is presented. If the approach is used, the requirement precision of antenna setting will be greatly reduced.
