Abstract: 1. In a fire control radar system of the character which produces radar signals having a predetermined repetition period and which includes coupled in cascade; an intermediate frequency amplifier, a second detector, a video amplifier, a junction, an angle tracking gate, a selective switch, an angle tracking amplifier and integrating circuit, and an error detecting circuit for providing antenna control signals; and including also an automatic gain control loop coupled between the selective switch and the intermediate frequency amplifier; the system being adapted to automatically home on radar signals reflected off a distant object; the combination therewith of means for homing on signals emanating from the distant object, said means comprising: a jammer gate circuit coupled between the junction and the selective switch and being adapted to pass to said selective switch signals impressed on said jammer gate circuit from said junction during the application of a long enabling pulse which is applied during the latter portion of the repetition period.
