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.
