ABSTRACT:
An underwater intrusion alarm system using an array of one or more remotely eployable, acoustic doppler detector probes. Each probe is a unitary submersible buoy formed by a pair of vertically coaxially and acoustically isolated, right cylindrical active transducer elements that are shielded from surface and bottom reflections. Transmitter and receiver circuits may be located either in the buoy with an external connection to conveniently located headphones and alarms or at a distant site with a fixed wire connection to the buoy transducer elements. A depth sensitive ancilliary mechanism regulates the submergence of the buoy in conformance with the rise and fall of the tide.
