Computational Modeling for Panel Adjustment of Large Reflector Antennas

In accordance with the characteristic that large parabolic reflector antenna surface is divided into panels, based on the concept of the best-fit paraboloid (BFP), a method for panel adjustment is studied from the viewpoint of branch crossing. The transformation matrix that relates adjustments to surface errors is derived. Based on the transformation matrix, a novel mathematic model and a useful program for guiding panel adjustment are developed to determine the adjustment quantity of reflector panels. After being used in practice the results have shown that the model is of precision.
