Kongsberg Maritime has introduced a new tow fish side scan sonar for use in Search and Recovery (SAR) missions as well as underwater inspection, engineering and scientific surveys. Developed by Kongsberg Geoacoustics and available now, PulSAR is designed for intuitive operation and easy deployment by non-specialised personnel, enabling effective short-notice surveys using vessels of opportunity.
The PulSAR system acquires high resolution acoustic images of the seabed using a compact, rugged stainless steel tow fish that is operated with a water protected (IP66) deck unit and small cable hand reel. The system can be deployed on small vessels such as open RIBs. Large areas can be surveyed efficiently revealing small objects and structures in great detail. PulSAR operates in a frequency range of 600 kHz to 1 MHz and both FM and CW source signals can be selected in order to optimise the range and resolution for the given survey task.
