Abstract	In sonar applications, the ability to locate underwater structures such as pipelines and a wreckage of submerged airplane is important. To investigate extensive sections of the seabed within a limited time period, the scanning speed and the reliability of object detection alarms are the most critical factors for finding objects. In this paper, we propose a method to provide an automatic detection alarm indicating the presence of suspected underwater objects using high-speed imaging sonar. The proposed method is based on the cross-correlations between two successive acoustic beam profiles of imaging sonar. The alarm signal alerts human operators or automatic underwater vehicles to suspected objects, which may be a part of or all of the target object. Using this signal as a trigger, the object can then be examined in more detail to determine whether it is the target. We verified the feasibility of the proposed method by indoor and field experiments.
