TELEDYNE RESON SEABAT 7125 8125 MULTIBEAM ECHOSOUNDERS
With unparalleled resolution and installation exibility, the SeaBat 7125/8125 is ideal for a great variety of hydrographic, offshore, military, bathymetric, sidescan & snippets applications from a surface vessel, ROV to 6000 meter depth.
The SeaBat 7125 is a single and / or dual frequency (200/400kHz) multibeam echosounder system. In the 200kHz conguration, the receiver forms 256equi-angle or equi-distant dynamically focused 1° receive beams to cover a 128° swath, with a maximum range of 500 meters. In the 400kHz conguration,the receiver forms 256 equi-angle focused 0.5° receive beams or 512 inequi-distant mode, to cover a 128° swath, with ultra high resolution and atypical range of 200 meters.
The SeaBat 7125 is controlled by the 7-P, a high performance Sonar Processor that manages data ow and signal processing using a state-of-the-art FPGA architechture. The 7-P provides a Windows®-based GUI user interface, allowing system conguration, control, data output, storage and built-in test environment(BITE) displays to assist the operator.
Equi-distant or equi-angular beam spacing across the entire swath is selectable by the operator to provide uniform sounding density and maximize usable outer swath. Data logging of beamformed water column data or pre-beamformed data to a RAID disk system is also optionally provided.The SeaBat 7125 receiver sonar head design provides increased bandwidth, improved dynamic range and noise immunity over earlier models and makes full use of Commercial-off-the-Shelf (COTS) hardware and software to increase cost effectiveness with a well dened path for future upgrades and expansion.
