1. In an angle tracking radar receiver, first means for generating a first signal representing the angular deviation relative to the radar tracking axis of a predetermined target, second means for generating a second signal representing the angular deviation relative to said axis of the target nearest the radar, means for comparing said first and second signals and for generating a first control signal upon the inequality of said first and second signals, means for sensing the closure within a predetermined range interval of said predetermined target and another target situated at lesser range, said means for sensing producing a second control signal upon said range closure, utilization signal generating means, and means for applying said first and second control signals to said last-named means to produce said utilization signal upon the concurrence of said first and second control signals.
