摘　　要：本文给出了一种计算抛物面索网天线型面精度与投影网格边长关系的方法。在天线反射面的光学口径面内,将其内接正六边形用正三角形进行划分,设定正三角形网格的边长,编制matlab程序,依次计算各区域对应的型面精度值,得到整个天线型面精度与投影网格边长的关系。通过与传统网面精度计算公式相比较,证明了本方法的有效性与正确性。This paper presents a method that can calculate the surface accuracy of parabolic cable antenna with projection of grid side length. Within the optical aperture plane antenna reflecting surface, divides the inscribed regular hexagon that using an equilateral triangle, sets the length of the equilateral triangle mesh side, prepares the matlab program, successively calculates the corresponding profile accuracy value of each region, gets the relationship between the surface accuracy of the entire antenna and the projection-type mesh side length. Comparing with the traditional formula of mesh accuracy, it proves the validity and accuracy of the method.
