Function Description
EdgeTech 3300 Hull Mount Sub-Bottom Profiler
The EdgeTech 3300 Hull Mount Sub-Bottom Profiler is a high-performance wideband FM sonar system designed for high-resolution imaging of sub-seafloor structures. Utilizing EdgeTech’s Full Spectrum® CHIRP technology, it offers superior signal resolution and penetration, making it ideal for geological surveys, geophysical research, environmental assessments, and more.
Main Features and Benefits:
- Exceptional Sub-Bottom Imaging Quality: The broadband CHIRP technology provides clear and high-resolution images of sub-seafloor strata, aiding in the identification and analysis of subsurface structures.
- Flexible Configuration Options: The system can be configured in various array formats (2×2, 3×3, 4×4, and 5×5) to meet different survey needs and vessel requirements.
- Full Ocean Depth Capability: Designed for use in both shallow and deep water, accommodating surveys across a full range of ocean depths.
- Enhanced Penetration with High Resolution: The CHIRP technology enables deeper sediment penetration while maintaining high-resolution imaging, suitable for a wide range of geological conditions.
- Multiple Pulse Processing: For deepwater surveys, the system supports the simultaneous transmission of multiple pulses in the water column, using height-based information to separate and analyze each echo, improving along-track resolution.
