ABSTRACT:
An improved system and technique for reducing interference in signal receng systems, particularly in sidelobe canceller systems. Adaptive canceller loops receive inputs from an auxiliary channel signal and operate on a main channel signal to reduce interference in the main channel signal. The auxiliary channel signal is supplied through a quadrature hybrid circuit to provide I and Q components to the adaptive loops, which loops are connected in series and cascaded such as to form a plurality of serially connected I and Q loops.
