摘要
介绍了标准旋转抛物面表面精度统计的方法,给出了FAST密云模型反射面表面精度计算的具体方法,得出了最优拟合精度及对应的焦比、平均径向误差等。
A method for statisticing the surface precision of standard paraboloid antenna is put fornar, and the caculating method of Miyun model surface precision is given. Based on the measurement datas, the precision of the spherical surface is calculates. According to the least square astimate principle, the optimum focus of the ellipse is calculates, which has the most high surface precision.
