Title: Jammer detection and tracking system

Abstract: A radar receiver adapted to detect and track a narrow band jammer is shown to include logic circuitry adapted successively to sense jamming signals from such a jammer to determine the extant frequency of the speed gate when the amplitude of the automatic gain control signal increases and to determine whether or not the received signals are coherent, and, finally, if the received signals are not coherent, to produce a tracking control signal effective to cause tracking of the narrow band jammer.
