1.2 System Architecture
The SeaBat 7125 SV2 multibeam sonar system consists of a combined sonar interface
and processing unit, known as the transceiver, as well as a receiver unit and a projector
unit, both with dual-frequency operation. 25 meter cables connect the receiver and
projector units to the transceiver. User displays and system control originate within the
transceiver.

digitized by internal electronics, and sent to the topside transceiver for beamforming and
