Abstract

The errors associated with a segmented primary reflector limit the electrical performance obtainable with those antennas which employ them.It is necessary to derive the effect of panel positional error on electrical performance in order to determine panel adjustments for such reflector antennas.The transformation matrix that relates panel adjustments to surface errors in terms of best fit paraboloid (BFP) is derived.Based on the transformation matrix

a novel mathematical model and a useful program are developed.After being used in practice the results have shown that the method for panel adjustment is of efficiency.
