  • Abstract
    Onboard magnetic compasses allow sonobuoys to measure their orientation and form beams along true headings. Compass failure means true array heading is unknown and the buoy´s beams cannot be used for target localization and tracking. We describe a method for recovering buoy orientation by inverting the pattern of signal arrivals at the individual hydrophones, and present results using data recorded at sea.
