| Abstract: | 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. |
