Echo Repeater Acoustic Source-ERAS


Transmit, repeat and test signals with the Echo Repeater Acoustic Source System (ERAS)


ERAS is a low cost, compact and flexible sonar test system. Designed for hand-deployment from small vessels, it contains both projector and hydrophone.


ERAS is controlled by an easy-to-use Graphical User Interface, commanding the Digital Signal Processing software to Echo Repeat, Transpond and produce calibrated complex transmissions.
