Atlas Elektronik’s Synthetic Aperture Sonar (SAS) has been designed and developed to meet the requirements of civilian survey markets providing a robust, high performance survey system that is easily integrated onto small platforms due to its compact and modular design.
Integrated survey solution – sonar hardware, SAS processing and survey mosaicing
Long range – rapid area coverage reduces survey time and cost
High resolution – exceptional image quality allows detection and identification of small targets
Constant Image Quality – Synthetic aperture processing provides constant resolution across the entire sonar swath
Low power –specifically designed to maximise AUV endurance
Proven technology – multiple units in-service with hundreds of hours of problem free operation
Compact – self-contained for ease of integration with host platforms
Low cost of ownership – No maintenance requirements
Vision 600 is a Synthetic Aperture Sonar (SAS) system suitable for integration into new or existing AUVs.
The system comprises an outboard sonar system, data storage, inboard SAS data processing and display system with connectivity to Automatic Target Recognition (ATR). Simple interface requirements are coupled with low power consumption and high capacity data storage allowing the operator over 12hr survey or reconnaissance operations.
The system is capable of processing data from various platform speeds generating full swath, geo-referenced images to the operator in real time. Imagery can be displayed using ATLAS UK’s Classiphi sonar display tool extensively used by the Royal Navy for post mission analysis. Alternatively, data can be exported in industry standard XTF format for display on customer facilities. The processing hardware can also be attached to a customer supplied networked storage device for data archiving. The SAS processing provides 200 metre wide image swaths at constant 25mm resolution.
This solution provides the next generation seabed survey with constant pixel resolution out to 100 metres. Vision 600 offers significant improvement in resolution over conventional sidescan technology.
The Vision 600 offers long range imagery with a resolution that is constant and significantly greater than conventional sidescan sonar:
