Common method of determining residual errors in pointing of paraboloidal-reflector microwave antennas involves constantly dithering antenna mechanically about estimated direction of source. For cases where expense of additional focal-plane collecting horns (and their amplifiers) justified, new method eliminates mechanical dithering. Outputs of multiple receiving feed horns processed to extract phase information indicative of direction of arrival of signal received from distant source.
