ABSTRACT:
This invention is directed to a modified monopulse comparator which includes two sum and difference hybrid junctions. The first hybrid junction produces a signal-free sample of any interference which is received by the datalink receiving antenna. The second hybrid junction is a standard monopulse comparator driven by amplified and filtered signals from the A and B antenna feeds after subtraction of the properly scaled and phased interference sample.
