Abstract
The effects of random phase errors are distinguished from the effects of large-scale phase errors or aberrations on the gain, main lobe efficiency, and beamwidths of reflector antennas. It is shown that one may determine the reflector tolerance only by separately evaluating the two types of errors, and an experimental procedure for accomplishing this by pattern range or astronomical measurements is described.
