In this paper, the geometry equation was educed for multibeam parabolic torus antenna. The theory of coordinate measure system and the computus of the least squares method, the calculation formula of target point standard direction error were mainly discussed. 导出了多波束天线的几何方程,讨论了坐标测量系统的原理、最小二乘法拟合计算方法,导出了观测点法方向误差计算公式,计算了观测点法向误差及均方误差。
The swinging angle detection of outside ball basket by using hydraulic drive system and sliding displacement detection of inside ball basket is indirectly achieved by detecting swinging angle and computus. 其中外球笼的摆角检测是用液压传动系统来实现的,而内球笼滑移量的检测则是通过检测其摆角来间接计算的。
