FIELD: detection of hidden metal objects.
SUBSTANCE: mobile device has receiver and signal processing unit which both are placed on operator's body and transmitting device. Receiver has two receiving coils. Signal processing unit has first and second preamplifiers which have inputs to be inputs of signal processing unit. Receiver also has adder. Transmitting unit has transmitting coil and oscillator. Phase shifter and amplitude regulator are introduced into signal processing unit and have to be significant feature of the device as well as two repeaters introduced into receiver.
EFFECT: increased s/n ratio; increased fidelity of detection.
