Abstract
Systems and methods are provided for automatically detecting sonar contacts. The system comprises a data analyzer that integrates the raw data from a plurality of sonar detectors over a predetermined period of time, thereby providing integrated data characterizing a sonar image on a sonar display. A Hough transform module is configured to employ a Hough transform algorithm that transforms at least a portion of the integrated data to detect a substantially straight line in the sonar image.
