Sonic 2024/2022 Receive (Normal Operation Mode)
The Projector is comprised of composite ceramics that convert electrical energy to acoustic energy.
The composite ceramics, in the Receive Module, convert the reflected acoustic energy back to
electrical energy. The small electrical voltage, generated by the ceramics, is amplified and then
passed onto the receivers. The output of the receivers goes directly to the Wet Controller board in
the Receive Module.
In general, the receive pattern is 130° (normal bathymetry survey) in the across-track. The along-
track pattern depends on the frequency; from 23° at 400 kHz to 40° at 200 kHz.

The Wet Controller board contains the FPGA that performs the beam forming and bottom detection
operation; time tags the data; and formats the sonar data for output back up to the SIM. The
bathymetry data is output as a Range and Bearing (from the sonar head’s acoustic centre) for each
beam. Other outputs include: side scan, beamformed imagery, and snippets.
The output of the Wet Controller board is sent through the deck lead, to the SIM’s Gigabit switch
and onto the data collection computer though one of the SIM’s external RJ45 connections.
