A Novel Algorithm for Ship Detection in SAR Imagery Based on the Wavelet Transform
(IEEE, 2005-04-30)
Article
Accés obertCarrying out an effective control of fishing activities is essential to guarantee a sustainable exploitation of sea resources. Nevertheless, as the regulated areas are extended, they are difficult and time consuming to ... -
Circular synthetic aperture radar (C-SAR) system for ground based applications
(IEE-INST ELEC ENG, 1997-05-01)
Article
Accés obertThe authors present an SAR system capable of obtaining radar images from measurements carried out with antennas that describe a circular trajectory centred outside the target region. The analytical formulation of the ... -
High-speed focusing algorithm for circular synthetic aperture radar (C-SAR)
(IEE-INST ELEC ENG, 2000-04-30)
Article
Accés obertA new algorithm is presented which is capable of generating very fast high-resolution images for circular synthetic aperture radar (C-SAR) systems. Its main characteristic is that it allows the processing of data from such ... -
Linear and nonlinear terrain deformation maps from a reduced set of interferometric SAR images
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-10-31)
Article
Accés obertIn this paper, an advanced technique for the generation of deformation maps using synthetic aperture radar (SAR) data is presented. The algorithm estimates the linear and nonlinear components of the displacement, the error ... -
On the extension of multidimensional speckle noise model from single-look to multilook SAR imagery
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-02-28)
Article
Accés obertSpeckle noise represents one of the major problems when synthetic aperture radar (SAR) data are considered. Despite the fact that speckle is caused by the scattering process itself, it must be considered as a noise source ...
