General Information
1.3 Hardware
Components
The five major components of the SeaBat 8101 system are described below.
Technical specifications and drawings are included in sub-paragraphs.
Sonar Processor
•
Sends DC power to the Sonar Head via the Signal and Control cable.
•
Sends control signals to the Sonar Head.
•
Receives and demultiplexes digitized hydrophone signals from the Sonar
Head.
•
Beamforms the received hydrophone signals.
•
Manages seafloor bottom detection.
•
Processes the bottom detection data for local display.
•
Processes the bottom detection data for export to peripheral systems such as
bathymetric data acquisition systems via an RS-232 interface or Ethernet
connection.
•
Receives and processes operator input.
•
Generates the graphical display.
Processor to Head Signal and Control Cable
•
Waterproof pressure-immune connector at wet end.
•
Single MS-type connector at dry end.
•
Conducts operating power for Sonar Head electronics.
•
Conducts control signals for Sonar Head electronics (downlink).
•
Conducts multiplexed digitized hydrophone signals to the Sonar Processor
(uplink).
•
Shields internal signals from vessel electrical noise.
Sonar Head
•
Converts received DC power from the Sonar Processor to circuit operating
voltages.
•
Generates and transmits acoustic pulses via the transmit array (projector).
•
Receives reflected acoustic signals via the receiving array (hydrophone).
•
Preamplifies and digitizes received acoustic signals.
•
Multiplexes and sends digitized received signals to the Sonar Processor via
the Signal and Control Cable (uplink).
Color Video Monitor
•
Displays received sonar intensity data in operator selectable color palettes.
•
Displays processed bottom detection data in real time.
•
Displays system status and control menus for operator interaction.
