  • The selection of minimum value of surface fitting is one of the key technologies refer to the antenna panel surface detection. The antenna surface root-mean-square of semi-optical path difference is an index of antenna surface accuracy. A direct calculation method of semi-optical path difference (OPD) was presented according to the geometric definition of conic surface and its optical properties. The nonlinear least squares curve fitting algorithm based on the semi-optical path difference was described. Employing a parabolic reflector panel as the sample, through simulation and actual measurements, the fitting results were contrastively analyzed while selected axial deviation and semi-optical path difference as minimum value respectively. The experiments verifying the fitting method based on semi-optical path difference is more precision and stability.
