Abstract : A regenerative radio-frequency wire detector is disclosed which incorporates a radio antenna and a radio receiver connected thereto. A radio transmitter is timely energized by an output signal from the aforesaid radio receiver which, in turn, causes the transmitting of electromagnetic energy within the environment ambient to the wire to be detected. A commercial radio station or other source is employed as a covert initial energizer of the wire to be detected. When so energized, said wire re-radiates electromagnetic energy to the receiving antenna which starts the regenerative processing within the system loop constituting the radio receiving antenna, the radio receiver, the radio transmitter, the transmitting radio antenna, the wire, and the environmental medium or mediums within which it is disposed. Due to the amplification effected by the aforesaid regeneration process, the detection of marine mine command wires, for example, is facilitated.
