Abstract
    NOAA’s Office of Coast Survey is seeking to ascertain whether current interferometric sonar technology is capable of meeting nautical charting hydrographic survey requirements for shallow water and nearshore survey work. Operational tests show that phase differencing sonar technology is capable of resolving ~I m3 sonar targets on the seafloor and sloped and vertical features up to the draft of the instrument while improving coverage efficiency by better than two times that achievable with shallow water multibeam in waters shoaler than 10m. Preliminary results are promising enough that NOAA hopes to move forward with system integration and operational test and evaluation aboard a NOAA hydrographic survey vessel during the 2006 field season.
