FSI - Model HMS-622 12KM -Hull Mounted Seismic Profiler
Deep water sub-bottom profiling applications (1Km to 12Km) require an array of 4 to 36 low frequency transducers installed in a hull-mounted sea chest. The HMS-12KM system with the HMS-622 CHIRPceiverTM and hull mounted transducer arrays fills this range of survey requirements. The frequency bands supported by the HMS- 12KM include LF (1KHz-10KHz) and HF (8KHz-23KHz) with a standard 2 channel transceiver. CW frequencies can also be programmed within the respective band. The transducer arrays are configured to perform both the transmit and the receive functions of the system. The transducers are wired to a junction box containing the SCP-10KM Software Controlled Preamplifier which is collocated with the sea chest and is permanently connected through a shipboard cable to a topside junction box which provides the interface to the HMS-622 CHIRPceiver and workstation.
The HMS-622 CHIRPceiver uses a flexible Graphical User Interface connected via Ethernet that allows the user to set CHIRP or CW modes of operation, Start and Stop frequencies, Pulse Lengths, and Power Level for the output pulses. The receiver controls allow for Gain and Attenuation as well as Diagnostic modes. The HMS-622 CHIRPceiver will also support multi-ping modes for higher along track resolution when operating in water depths deeper than a given ping rate. All sonar data is logged in SEGY format using industry standard acquisition
software.
