ABSTRACT:
An oscillator control circuit for controlling the "on" time of a repeater untermeasure radar having a plurality of oscillators, each generating a portion of a lobing frequency band covering an unknown lobing frequency expected from an enemy radar, the outputs from which are conducted through an AND circuit. The AND circuit can be mechanized to produce the required switching function whenever the several portions of oscillators all are either greater or less than a predetermined value to produce an output signal to switch the repeater countermeasure "on" for enemy radar deception, the sweep time of the plurality of oscillators over their respective partial bands being adjustable.
