FIELD: radioelectronics, applicable for location of radioacoustic beacons-responders, mainly in rescue operations on water.
SUBSTANCE: the system has an acoustic radiator, responder beacon, radio-frequency switch, radio receiver, low-sensitivity microphone, control unit, indicator.
EFFECT: simplified construction due to rejection of use of a power amplifier and electroacoustical-electrical transducers without worsening of other indices of the system quality.
