Abstract

In side-lobe cancelling equipment direct jammer signals appearing in an auxiliary antenna channel are better correlated with reflected jammer signals in a main antenna channel by splitting the signal in the auxiliary channel into two parts, one of which is directly correlated with direct jammer signals in the main channel and the other is passed through a delay line to alter its timing to match the timing of the reflected jammer signals in the main channel.
