PulSAR: New SSS for SAR Operations

Posted by Irina Tabakina

A new tow fish side scan sonar has been introduced by Kongsberg Maritime for use in search and recovery (SAR) missions as well as underwater inspection, engineering and scientific surveys. Developed by Kongsberg Geoacoustics, PulSAR is designed for intuitive operation and easy deployment by nonspecialized personnel, enabling effective short-notice surveys using vessels of opportunity, the developer said.
The PulSAR system is designed to acquire 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 optimize the range and resolution for the given survey task. PulSAR is battery or mains powered, using 24 VDC or 110/230 VAC. It has an integrated GPS system that provides positioning information with SBAS differential corrections and an external positioning system can be connected via a serial port.
The system is delivered with a dedicated software package to be run on a laptop computer connected via Ethernet to the deck unit. It allows the user to plan and conduct the survey and acquire sonar data with embedded positioning information.
