GEOACOUSTICS TOWED DSSS (DIGITAL SIDE SCAN SYSTEM)
This highly advanced system allows precisely repeatable seabed feature mapping in a robust and reliable package. The system utilises high resolution direct digital sampling of the received signals, and full digital processing. This new technology offers unprecedented resolution and dynamic range (24 bit), simultaneous dual frequency operation (114/410 kHz), digital ïlters, pulse width auto adjust to optimise for any sample rate setting and a new high speed digital data link enabling very long lengths of low drag co-axial tow cable to be used. h.
Deck Unit – GeoAcoustics Universal Transceiver
The GeoAcoustics Universal Transceiver contains power supplies and all connections and interfaces to power the tow ïsh down the tow cable; to facilitate bidirectional communication for control and status reporting: and to transfer data from the tow ïsh. The ultra high dynamic range means that no user controls are necessary to acquire raw digital data of the highest possible quality. Side scan images can be processed in real time from this raw data using the DSSS-Viewer software package provided with the system.
