Signal Direction - of - Arrival and Amplitude Estimation for Multiple - Row Bathymetric Sidescan
In practical applications with bathymetric sidescan sonars, the multipath reflections and other directional interferences are the key limiting factors for a better performance. This thesis proposes a new scheme to deal with the interferences using a multiple-row bathymetric sidescan sonar. Instead of smoothing the measurements over some time or angle intervals, which was previously widely inves...
متن کاملHow Useful Is Bathymetric Information in the Classification of High Frequency Sonar Surveys?
In a number of sonar studies, bathymetric information is used to correct and visualise amplitude data. This work proposes a method which combines amplitude features (describing backscattering strength and sonar texture) with bathymetric features (indicating seafloor variability) for sonar classification. Features are selected per window (of user defined size) and areas around grab samples in a ...
متن کاملDeep Ocean Bathymetric Imaging with GLORI-B
This paper describes the bathymetric imaging and pro cessing of the GLORI B system GLORI B is a deep ocean sidescan sonar surveying device which is able to produce bathymetry measurements and images of the sea oor in swaths of up to km wide The basics of the GLORI B system are described and then the vari ous stages of processing the received data to transform it into a geographically registered...
متن کاملActive and Adaptive Dive Planning for Dense Bathymetric Mapping
We examine the problem of planning dives for an Autonomous Underwater Vehicle (AUV) to generate a dense bathymetric map using sidescan sonar. The three key challenges in this scenario are (1) proper modeling of the local uncertainty of the 3D reconstruction, (2) efficient dive planning to reduce this uncertainty, and (3) determination of when to re-plan adaptively based on new information. To a...
متن کاملCalibration of Textural Analysis Parameters towards Valid Classification of Sidescan Sonar Imagery
In this paper textural parameters resulted from grey level co-occurrence matrices (GLCMs), first order statistics and Fourier power spectrum techniques are used to develop an adaptive and simple to use, texel based classification method for sidescan sonar imagery. Sonar imagery contains textures with no distinct acoustic signatures that moreover vary in space due to many reasons. In addition, G...
