ABSTRACT:
A first extended interactive amplifier operates at a fixed frequency while a second such amplifier sweeps across a frequency range. The respective extended interactive amplifiers produce individual signals which are fed through separate waveguides to corresponding horns of an antenna. The frequency separation of the produced frequencies is made to match a threat radar's IF channels. By setting the jamming signal frequencies well above the threat radar band, the mixers of the threat radar receiver generate grossly unbalanced angle error signals. This disturbs the capability of the threat from homing in on the jamming site. Accordingly, the resulting jamming signal provides excellent electronic countermeasures.
