The radome causes an angular displacement of the tracking aerial polar diagram.
天线罩使跟踪天线的极图产生了角位移。

It is convenient to apply diagram multiplication when structure displacement is calculated, but faults easily occur if its applying conditions and characteristic are ignored.
应用图乘法求结构位移比较简便，但若忽略其适用条件和特点，将导致计算出错。
