Sidescan sonar imagery processing software for underwater research

OCEANS 2011 IEEE - Spain, 2011
Detailed submarine digital analysis of side scan sonar images significantly enhances the ability to assess seafloor features and artifacts digital images. These images are usually poor in their resolution if they are compared with optical images. There are commercial solutions that could solve this trouble, such as: the use of high resolution multibeam

Performance Evaluation of a 3-D Sidescan Sonar for Mine Countermeasures

OCEANS 2018 MTS/IEEE Charleston, 2018
This paper describes an evaluation of a 3-D sidescan sonar system, the Ping DSP 3DSS, for mine countermeasures (MCM) applications. Testing trials were performed over seabed and moored mid-water targets, with the mid-water targets being the focus as this ...

Sidescan sonar detection performance with PRN coded signals

Proceedings of OCEANS '93, 2002
A sonar transmission signal that has enhanced the operation of conventional 50 kHz depth sounders in noise-limited environments has been applied to a sidescan sonar application where the acoustic background is dominated by reverberation. By transmitting a pseudorandom noise (PRN) source pulse with a high bandwidth-time product, and detecting the ...

Sidescan sonar: a directional filter of seabed texture?

IEE Proceedings - Radar, Sonar and Navigation, 1999
As the exploration of the seafloor is extended ever further, automated classification and interpretation of sonar images are becoming increasingly important. However, many of the image processing techniques employed for these purposes consider the images simply as a collection of textures and neglect the process by which these images are formed.

Sidescan Sonar Observation of Bedform/Mine Interactions

2001
Abstract : Our research program focuses on identifying and quantifying sediment erosion, transport, and deposition processes on the continental shelf through state of the art observational techniques in both fine grained and sandy environments. In sandy environments our goal is to understand the detailed interactions and feedbacks between hydrodynamics,
