- W2366827075 abstract "The data processing methods of surface antenna's calibration are deeply discussed in this paper. There are two steps from 3D measuring coordinates to useful information (for example, surface accuracy): coordinate transformation and surface accuracy calculation. The first step is more important. Three methods (surface free transformation, common point coordinate transformation and CAD surface transformation) are discussed in this paper. The mathematic models and formulas of these methods are deduced and some results are given finally. According to the theoretical analysis and actual calculation we can see that the CAD surface model fitting is the best method because it needs neither the surface equation nor common point but the CAD surface and its result is reliable. If there is no CAD surface model but a number of common points, then the common point coordinate transformation is a better method, but its result would be influenced by the accuracy of common points. If there exists neither CAD surface model nor common point or the accuraey of common points is low, the surface free fitting is also a good method, which has a high surface precision but the calculated surface might be shifted." @default.
