Abstract

Aircraft receives the enemy radar signals, amplifies them and transmits the signals forwards and towards the ground or sea in a direction towards the attacking missile which carries a target search radar. This signal is much stronger than the direct echo signal from the aircraft thus missile deviates from original flight path. The radar system includes an antenna network capable of being controlled to point in required direction. The system will operate at relatively low altitude.
