At-sea measurements of diver target strengths at 100 Khz: measurement technique and first results
Hollett, Reginald D.; Kessel, Ronald T.; Pinto, Marc A. (NURC, 2006/08)During a recent at-sea trial of a diver detection system, the opportunity was taken of developing a technique for in-situ measurement of diver target strengths. The technique was based on making the diver perform circular ... -
Autofocusing a synthetic aperture sonar using the temporal and spatial coherence of seafloor reverberation
Pinto, Marc A.; Fohanno, F.; Tremois, O.; Guyonic, S. (NATO. SACLANTCEN, 1997)An autofocusing algorithm for the compensation of translational motion errors of a sea floor rmaging synthetic aperture side scan sonar is presented. The algorithm does not depend on the presence or absence of dominant ... -
Automatic change detection for the monitoring of cluttered underwater areas
Coiras, Enrique; Groen, Johannes; Evans, Benjamin; Pinto, Marc A. (NURC, 2008/09)Automating the surveillance of cluttered underwater areas (such as ports) poses several problems, the main one being the high number of contacts that any automatic target recognition (ATR) system will produce when surveying ... -
AUV technology for shallow water MCM reconnaissance
Evans, Benjamin; Baralli, Francesco; Bellettini, Andrea; Bovio, Edoardo; Coiras, Enrique; Davies, Gary L.; Groen, Johannes; Myers, Vincent; Pinto, Marc A. (NURC, 2007/10)The ability to perform MCM reconnaissance missions in shallow water is important in both expeditionary MCM and in the protection of ports against maritime improvised explosive devices (MIEDs). For many years AUV systems ... -
Design of synthetic aperture sonar systems for high-resolution seabed imaging (tutorial slides)
Pinto, Marc A. (NURC, 2006/10)This tutorial reviews the key aspects of the design of synthetic aperture sonar (SAS) systems for -
Experimental results of 300 kHz shallow water synthetic aperture sonar
Bellettini, Andrea; Pinto, Marc A.; Evans, Benjamin (NURC, 2007/11)The design of a shallow water synthetic aperture sonar (SAS) requires an understanding of key system and environmental issues. The main factors which limit SAS performance are micronavigation accuracy, where micronavigation ... -

Shallow water synthetic aperture sonar: an enabling technology for NATO MCM forces
Pinto, Marc A.; Bellettini, Andrea (NURC, 2007/10)The change in military focus from Cold War doctrine to expeditionary operations in shallower littoral water and the heightened terrorist threat to ports and their approaches, have put increased emphasis on countering ...
