The objective of the project is to develop an early warning system for detecting ice and characterizing the level of threat for oil and gas operations in Arctic regions. The innovative technology, consisting of coherent radar technology and state-of-art s ignal processing software, will be capable of monitoring ice, waves and currents with significantly improved accuracy compared to existing, non-coherent marine radar systems. The consortium partners Nortek (instrumentation), North Atlantic Drilling (offsh ore drilling company), Statoil (oil & gas), Norsk Polarinstitutt (Arctic research) and University of Oslo (numerical modeling) have a genuine commercial and technical interest in succeeding with the new technology as this will improve maritime safety. Th is solution differs from standard radar systems in that it utilizes coherent radar, which provides an enriched data. Coherent radar data allows the use other criteria for small target detection in the presence of substantial background clutter. Ice such as "growlers" and "bergy bits" have a small surface expression relative to their total volume. This stealth characteristic makes them difficult to detect and a serious safety issue for Arctic operations. Coherent radar signal allows to directly estimat e the radial velocity. This is an aid for tracking ice velocity, but the greater benefit is the ability to (a) estimate radial components of surface currents, and (b) estimate wave height. Wave height has historically been challenging to estimate with ra dar, particularly standard marine radars. These new capabilities will become the state of the art for environmental monitoring. To reach this goal much effort will focus on understanding the surface response to radar and identify error sources.Algorithm s for the wave inversion problem and target detection will be developed baseed on a solid understanding of the mechanism. The system will be a software solution that employs the benefits of coherent radar.
