Welcome to the IMI30 Home Page!
Welcome! The Hawaii Mapping Research Group (HMRG) has been funded by the U.S. National Science Foundation to build and operate IMI-30, a deep-towed 30kHz phase-difference bathymetric sidescan sonar (OCE-0097822 ). The system will simultaneously acquire true sidescan sonar imagery, phase difference bathymetry, and multibeam subbottom data, with the ability to host other user-supplied instruments as well (such as towed magnetometers).
IMI-30 will be functionally similar to the HAWAII MR1 and DSL-120 towed sonars, sharing fundamental electonics characteristics, data acquisition computers, and sonar processing software. These shared characteristics resultin lower costs for each system, and a larger pool of engineers, technicians and scientists familiar with the maintenance, operations, and data processing requirements of this family of sonars. IMI-30 will be designed to be fully portable for use on any class I or II UNOLS vessel, and on other suitable vessels of opportunity. Once operational, IMI-30 will be offered to all NSF researchers as part of the University of Hawai`i shared-use equipment pool.
