| Abstract: | Simrad EM multibeam sonar systems have echo intensity as part of their data output.The systematic gain in collecting these data is analyzed.The content and significance of echo intensity showed by depth datagram and sonar image datagram are respectively explored.The recording pattern,characteristic and applied scope are studied at last.The founding will provide exact and clear basic data in underwater target identification and seafloor classification by multibeam sonar systems. |
