SBP29
Sub-bottom profiler
The SBP29 is the next-generation narrow beam sub-bottom profiler and is the successor of the successful SBP120 and SPB300. The system has new and improved technology, wider bandwidth (2 to 9 kHz) and improved range resolution.
Advanced Sub-Bottom Imaging
The primary application of the SBP 29 is to do sub-bottom imaging of sediment layers and buried objects, The data can be stored as raw or in SEG-Y format. A high source level improves the signal to noise ratio, which is further augmented by system properties that affect image quality such as narrow beam width, range resolution limited by the signal bandwidth, and a high source level.
Electronic Stabilization and Beam Features
The SBP 29 beams are electronically stabilized for roll and pitch, and the data are heave compensated. It can operate with wider beams, thereby trading slope robustness for signal quality. The array geometry is akin to that used by EM multibeam echo sounders, employing the wideband receive antenna of the EM system. Much narrower beam widths than conventional sub-bottom profilers are utilized, delivering superior specular return to backscatter ratio for improved penetration and less cluttered imaging.
Transmit Modes
The SBP 29 has two innovative transmit modes as tools when sloping sediments is a problem: one allows cyclic variation of the beam widths, while the other offers volume scanning with narrow beams. A swath of beams per ping provides across-track slope robustness. These swath beams are also beneficial for the detection of buried objects and backscatter studies.
Key features
- High source level, adjustable down by 30 dB in 1 dB steps
- Narrow beams for improved penetration, cleaner data, and good angular resolution
- Capability to create wider beams as needed
- Generation of a swath of beams per ping for acrosstrack slope robustness and detection of buried objects, also aiding backscatter studies
- Transmit modes for when narrow beams are unfavourable, including cyclic variation of beam width and alongtrack beam tilt (volume scanning)
- Typically operated in parallel with the EM system, either synchronized or unsynchronized
- Burst and multi-pulse modes to maintain a high ping rate in deep water
