Receiver-amplifier unit МПУ
FUNCTION
The receiver-amplifier unit is designed for receiving hydro acoustic signals, converting these signals into electrical ones and then amplifying them
APPLICATION
Receiver-amplifier unit can be used as a component of extended antennas designed for detecting sources of radiation of acoustic signals:
♦ Fishing-boats;
♦ Coast zone guarding systems;
♦ Failure detection systems for oil and gas pipelines.
