Abstract
An angle set on apparatus for an electronic countermeasure system utilizing a single dual mode phased array antenna which is operated under receiver/processor control to serve as both a transmit and receive element thereby avoiding the need for a separate direction finding system and, since transmit and receive functions share the same antenna, eliminating the need for precision pointing accuracy. The receiver/processor unit would continue to identify emitters using the jamming unit's receive antenna element and, where appropriate, PRI trackers would be assigned. The time of arrival window would then be used to blank the transmitter signal and to switch the phased array to the receive mode. During sequential time of arrival windows the receiver/processor would vary the pointing angle of the phase array until the emitter angle of arrival is determined and stored in memory. At periodic intervals in the future, the receiver/processor unit would again output a time of arrival blanking window and update the stored angle of arrival. During all other time of arrival windows the beam would be pointed to the stored angle of arrival value for high effective radiated power jamming.
