Side scan sonar and interferometric noise

Oceans '99. MTS/IEEE. Riding the Crest into the 21st Century. Conference and Exhibition. Conference Proceedings (IEEE Cat. No.99CH37008), 2002
This paper concerns the description of different noise sources encountered as well as the impact of each of these sources through sonar interferometric data acquisition. The impact of noise is directly linked to the ability of the Vernier device to determine the 2/spl pi/ ambiguity of the phase measure and to know the altitude of the bottom.

Bistatic side scan sonar

The Journal of the Acoustical Society of America, 1992
This discloses an improved side-scan sonar capable of locating objects on e ocean floor including the strip directly beneath the sonar transmitter and receiver, which in prior arrangements had to be obtained by another pass. The arrangement includes a platform having acoustic transmitters spaced apart a substantial distance on either side of acoustic ...

Intensity correction of Side-Scan Sonar images

Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA), 2014
This paper presents a new method to remove the effects of uneven ensonification in Side-Scan Sonar (SSS) acoustic images, facilitating their use in underwater robotics. A Lambertian model is used for the sonar scattering process, relating the received echo with the ensonification intensity, the sea bed reflectivity and the incidence angle.

A new generation side scan sonar

OCEANS '88. 'A Partnership of Marine Interests'. Proceedings, 2003
Side-scan sonar traditionally has used a graphic paper recording system for the display and annotation of the data. A novel side-scan system specifically designed to use color video as the primary data display is described. Several design considerations and tradeoffs are discussed, some of which are unique to a system using a video display.

Object detection in side scan sonar

SPIE Proceedings, 2015
Automatic target detection is a challenging task as the response from an underwater target may vary greatly depending on its configuration, sonar parameters and the environment. We propose a Z- test algorithm for target detection in side scan sonar image which avoids this problem that covers the variation in the target response.
