    Abstract
  • In order to avoid the physical interference and reflecting surface deformation caused by a single reflector edge error, and ensure the final surface accuracy and electrical performance of large-scale compact range, an unified orthogonal distance regression model taking account of the typical forms of compact range(CR) reflection surface was proposed based on the evaluation of single reflector panel edge profile tolerance. And this model was employed to calculate the panels' nominal size, interference error and edge correction.Meanwhile this model also could be used to predict and mend the overall gaps interference high risk area. The single reflector's edges of a large compact range were measured by a laser tracker. After analyzing and correcting the high interference risk areas through the above approach, the CR gaps satisfied the design index of (0.4±0.2) mm.
