Abstract : The patent relates to a counter-countermeasures system designed to reduce the effectiveness of a so-called 'jamming' signal transmitted by an airborne enemy target in order to decoy a missile launched from an aircraft with the intention of impacting such target. The invention is intended to be employed in conjunction with apparatus on the missile for tracking the target by receiving the doppler frequency wave therefrom. The essence of the concept is the provision of means for discriminating between this true doppler signal from the target and a false doppler signal generated by the target and transmitted therefrom on a frequency which differs from the basic doppler frequency.
