FIELD: radio engineering, communication.
SUBSTANCE: device consists of a probing signal transmitter, receivers tuned to double and triple the frequency of the probing signal, a control unit, a processing unit, a control and display panel, an antenna unit, a broadband receiver, a spectrum analyser and a display for the spectrum analyser, connected to each other in a certain manner.
EFFECT: high information value when scanning an area for radio-controlled explosives by detecting an oscillatory circuit in the inspected facility and determining resonance frequency thereof.
