Acoustic beam profile-based rapid underwater object detection for an imaging sonar
'Springer Science and Business Media LLC', 2019Co-Authors: Cho H, Akira Asada, Joe H, Yu, Son CheolAbstract: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.In sonar applications, the ability to locate underwater structures such as pipelines and a Wreckage of submerged airplane is important.

Experimental results of rapid underwater object search based on forward-looking imaging sonar
2015 IEEE Underwater Technology (UT), 2015Co-Authors: Jeonghwe Gu, Soncheol YuAbstract:In case of marine accident, the rapid search for missing object such as an underwater Wreckage is one of the most important tasks. For this task, an autonomous underwater vehicle (AUV) that equips forward-looking imaging sonar can be utilized. The search task is accomplished by the following strategy. In the first phase, the AUV scans the target underwater area in a fast speed, and detects some suspected objects. In the second phase, the AUV approaches to the object and investigates it to determine whether the suspected object is the target object to be found. This paper provides experimental results of underwater object search in a fast speed for realizing the first phase of the strategy.

Mobile phone auto registration to OpenBTS-based cellular network in disaster situation
2014 8th International Conference on Telecommunication Systems Services and Applications (TSSA), 2014Co-Authors: Elvanno Hatorangan, Tutun JuhanaAbstract:When disasters occurs, cellular network might be down and cannot serve subscribers anymore. On the other hand, many victims trapped in a Wreckage might still have access to their mobile phone. An OpenBTS-based cellular network has been long before known as an ideal solution to rapidly deploy emergency GSM cellular network in situation after disaster. The problem arise when victims' mobile phone only associated to the providers' network where the SIM card come. Even though it can manually associate to available network in an emergency situation, but victims' situation and knowledge might prevented them in doing that. In this work we propose method to enable mobile phones automatically associates themselves to OpenBTS-based cellular network.

Mobile phone location logging into OpenBTS-based cellular network in disaster situation
2014 8th International Conference on Telecommunication Systems Services and Applications (TSSA), 2014Co-Authors: Elvanno Hatorangan, Tutun JuhanaAbstract:When disasters occurs, cellular network might be down and cannot serve subscribers anymore. On the other hand, many victims trapped in a Wreckage might still have access to their mobile phone. An OpenBTS-based cellular network has been long before known as an ideal solution to rapidly deploy emergency GSM cellular network in situation after disaster. We propose to deploy a mobile OpenBTS along with search and rescue operation. While the search and rescue team doing their jobs, the OpenBTS serves the victims mobile phone. The victims in limited space and time might access the OpenBTS system to try to send short messages (SMS). In this paper we propose a method to logging the location of received SMS to OpenBTS, so the disaster stakeholders will have way to find the possible victims location at later time.
