Keywords : SONAR ;Ocean Monitoring;Image reconstruction
Abstract : Ever since the CAT scanner technique for medical imaging was introduced, the fields of tomography and image reconstruction from slices have been gaining in popularity. Towards the end of the last decade, the application of tomogaphic method to large scale ocean monitoring was explored. This paper surveys the application of tomographic methods to ocean monitoring and surveillance. |
