March 2005GeoDAS GUI Overview New GeoDAS Features: Survey / way-point Layout (2-D)

March 2005GeoDAS GUI Overview New GeoDAS Features: SmartSonar Issues: Sensor complexity overwhelms operators –Too much to adjust: range, gain,pulse-width, etc Operators may not be present (AUV) –how do we tune for unknown terrain? Better raw data would give better input to ATAR –And give better raw data for survey SAS makes ATAR mandatory –If we can detect in raw element data, may note even need SAS Status: CEROS (Centers of Excellence for Research in Ocean Sciences) (DARPA $$) funded development of automatic sonar tuning, and target recognition Scheduled for release Fall of 2005
