Abstract

A system comprising a first electroacoustic transducer connected to an interrogation unit and at least one second electroacoustic transducer connected to a resonator, wherein the first electroacoustic transducer and the second electroacoustic transducer form an acoustic channel and the second electroacoustic transducer forms with the resonator a passive cooperative target which, upon receiving an interrogation signal from the interrogation unit, transmits a response signal via the acoustic channel, and the interrogation signal has a higher energy than the response signal.
