ABSTRACT:
An improved interference cancelling system and technique for optimizing sal sampling, particularly in a side-lobe canceller system operating in a multiple signal environment. A plurality of auxiliary antennas provide samples of the interference environment for cancelling interference received by a main radar antenna. At least one of the auxiliary antennas is rotated in a circle in a horizontal plane for causing modulation of the interference residue. The component modulated with the frequency of rotation in the residue is compared in phase with the rotation modulation frequency to derive a signal for automatically moving the antenna to a position in the horizontal plane where the residue modulation is substantially eliminated. At that position the cancellation is maximized for the particular geometry of interference sources at that time.
