5203 |a"This report describes work that was performed at National Research Council Institute of Ocean Technology (NRC IOT), St John's, in February 2012. There were several overall aims of the testing: to assess the suitability of the sensors for detecting small foreign objects on ship hulls or other underwater structures; to assess the true resolving power of the sensors; to assess optimal geometries for deployment of the sensors; and to provide high quality sonar data for ongoing imaging sonar data mosaicking software development. During the testing a variety of small imaging sonars were transited above small targets laid on the bed of the tank. Having the sonars mounted to the tow carriage of the test tank allowed precise control of the sensor–target geometry which is critical for achieving the stated trial goals. The purpose of this report is to document the testing that was performed for later reference, to assist in interpretation of the collected sonar data in later analysis"--Abstract, page i.
