A passive target detecting system for discriminating against off-target radars. A signal from the missile guidance representing the pulse repetition frequency of the target being tracked is combined in a coincidence circuit with the signals received by the target detecting device.
In a target detecting device of the passive type for use in a guided missile the combination comprising: (a) signal receiving means for receiving signals from radiating targets for producing negative and positive output pulses, (b) missile guidance circuit means for receiving signals from radiating targets and producing output signals representing the pulse repetition rate of the target radar of interest. (c) an “and”gate circuit having a plurality of inputs and an output, (d) first gate signal generating means coupled to said signal receiving means and ...
