Neural Volumetric Reconstruction for Coherent Synthetic Aperture Sonar
ACM Transactions on Graphics (TOG), Volume 42, Issue 4Article No.: 113, Pages 1–20https://doi.org/10.1145/3592141Synthetic aperture sonar (SAS) measures a scene from multiple views in order to increase the resolution of reconstructed imagery. Image reconstruction methods for SAS coherently combine measurements to focus acoustic energy onto the scene. However, image ...

Research on phase compensating factor of chirp scaling algorithm in multiple-receiver synthetic aperture sonar
ICIIP '16: Proceedings of the 1st International Conference on Intelligent Information ProcessingArticle No.: 20, Pages 1–6https://doi.org/10.1145/3028842.3028862Synthetic aperture sonar (SAS) imaging with multiple-receiver techniques can obtain high mapping rate and high azimuth resolution synchronously, however, it might also lead to a complexity of algorithm processing. Regarding the multi-receiver SAS ...

Data-driven image registration for coherent change detection of synthetic aperture sonar imagery
IVCNZ '14: Proceedings of the 29th International Conference on Image and Vision Computing New ZealandPages 196–201https://doi.org/10.1145/2683405.2683455Coherent change detection of synthetic aperture sonar images requires more accurate registration than can be provided by recorded navigation data. Instead, data-driven techniques must be used. This paper proposes measuring the position of correlation ...

Image registration of simulated synthetic aperture sonar images using SIFT
IVCNZ '14: Proceedings of the 29th International Conference on Image and Vision Computing New ZealandPages 31–36https://doi.org/10.1145/2683405.2683407The scale-invariant feature transform (SIFT) algorithm is investigated for registration of two synthetic aperture sonar images. The image registration geometry for two ideal sonar tracks is presented. The sonar track parameters (and thus the ...

Synthetic aperture bathymetry estimation with a multielement array
IVCNZ '12: Proceedings of the 27th Conference on Image and Vision Computing New ZealandPages 364–369https://doi.org/10.1145/2425836.2425907Bathymetric estimation from multiple synthetic aperture sonar (SAS) images is challenging for shallow water environments with low frequencies. This is due to the multipath echoes corrupting the desired direct-path echoes. In an attempt to suppress some ...

The Integrated Navigation Underwater Used in SAS Motion Compensation
ICICTA '09: Proceedings of the 2009 Second International Conference on Intelligent Computation Technology and Automation - Volume 03Pages 813–816https://doi.org/10.1109/ICICTA.2009.662Synthetic aperture sonar imaging is based on the straight track model with constant velocity. The motion estimation needs to be done for ascertaining the ideal track. It is usually be achieved by the integrated navigation with high precision. In this ...

The research of integrated navigation applied to synthetic aperture sonar underwater
WiCOM'09: Proceedings of the 5th International Conference on Wireless communications, networking and mobile computingPages 2165–2168Motion compensation of synthetic aperture sonar (SAS) needs resort to the integrated navigation which can give the position, velocity and attitude of SAS. This paper discussed the inertial navigation system composed of SINS, the Doppler velocity log (...
