Abstract: The high precision of antenna reflector panels is the key to develop the technique of high performance compact antenna test range. A new technique of contour adjustment for high precision sandwich reflector panels was developed. The principle of the contour adjustment of panels was analyzed. The core technology problems such as the decision of adjustment points- position and number, the adjustment value on each points were proposed. By use of numerical simulation, how many and where the adjustment points should be were determined. The algorithm for adjustment value calculation was verified by experiments. A contour adjustment device was designed and developed. Numerical simulation and experiments of contour adjustment were conducted against all possible shape error distribution. The results show that, by use of the adjustment device and the proposed core technique, the contour of panels can be adjusted effectively and the contour precision can be improved greatly. Additionally, contour adjustment technology makes it possible to use for the panels with bigger size and higher contour precision, to increase the qualified rate of finished product obviously and to improve the maintenance performance of reflector panels.
