Understanding Mechanically Scanned Imaging Sonars
2010The purpose of this chapter is to give a brief introduction to the operational principles of MSISs by explaining the basics behind the acquisition of acoustic images as well as providing tools to understand and interpret the information they contain. Moreover, some hints about the principal issues associated with managing MSIS data are given at the end

IEEE Transactions on Instrumentation and Measurement
Forward-looking sonar is a commonly used underwater detection device. However, due to the complex underwater environment, small target areas, and blurred features, the detection accuracy is poor and not conducive to quickly finding the desired targets ...

Application of HDR imaging techniques for sonar images
2012 IEEE International Conference on Computational Intelligence and Computing Research, 2012High Dynamic Range — HDR high resolution recording and processing are required for sonar images when the electronic noise floor from the sensor arrays is well below the ambient acoustic noise floor in the ocean in the frequency bands of interest, while maximum signal levels are determined by the transmitted source level used for the system. Practically

Unsupervised Markovian segmentation of sonar images
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002This work deals with unsupervised sonar image segmentation. We present a new estimation segmentation procedure using the an iterative method called iterative conditional estimation (ICE). This method takes into account the variety of the laws in the distribution mixture of a sonar image and the estimation of the parameters of the label field (modeled ...

Synthetic aperture sonar applied to a multibeam volume imaging sonar
The Journal of the Acoustical Society of America, 2004The possibility of using synthetic aperture sonar (SAS) processing techniques on a multibeam volume imaging sonar (the Buried Object Search Sonar, or BOSS) is explored. A system algorithm is developed which involves first forming several parallel synthetic apertures from a translated array oriented in the cross-track direction, then beamforming the ...
