Beam riding systems use a target tracker whose purpose is to maintain the antenna boresight pointing at the centre of the reflecting area of the target . 波束制导系统使用一个目标跟踪装置，它的目的是保持天线视轴指向目标反射的中心。
2.
The previous discussion addressed the theory required to compute the relative phase shift between adjacent radiating elements in order to position the beam of an array - type antenna to a specific angle off of the antenna boresight axis 前面的讨论中给出了计算使阵列天线的波束相对天线视轴线偏移一个给定角度所需的相邻单元间相对相移的理论。
