摘　　要：文中结合陀螺自稳定方法和定义的天线波束坐标系,分析了载体运动对波束指向和极化的影响,推导出了稳定隔离方程,实现了波束指向和极化的稳定。针对陀螺、动中通天线板和波束间的位置关系,对波束预倾斜情况下的两种陀螺安装方案分别进行了稳定隔离方程的推导分析,结果表明:两种安装方式结构简单,容易实现,其角速率补偿量与预倾斜角的关系因安装方法而异。According to the gyro self-stabilization method and the concept of the defined antenna beam coordinates system,the influences on pointing and polarization of the beam caused by the carrier＇s attitude variation are analyzed, and the stabilization isolation equations are deduced, so the stabilization of the beam＇s pointing and polarization are realized. Considered the relative position of the gyros, SOTM planar antenna and the beam, the stabilization isolation equations of two gyro installing schemes are deduced and analyzed based on the tilt beam. The results show that two schemes all have simple configurations and can be easily realized, and the relationship of the angle rate compensation and the tilt angle is different in the two schemes.
