Interferometric Synthetic Aperture Sonar
Interferometric Synthetic Aperture Sonar (ISAS) offers the possibility of high resolution, three-dimensional images of objects on the ocean floor. The height of objects is identified from the phase difference between two synthetic aperture images of the object obtained using two receivers separated by a short distance. A central problem is the need to unwrap the phase difference in the presence...
متن کاملSynthetic Aperture Sonar Imaging via One-Way Wave Equations
We develop an efficient algorithm for Synthetic Aperture Sonar imaging based on the one-way wave equations. The algorithm utilizes the operator-splitting method to integrate the one-way wave equations. The well-posedness of the one-way wave equations and the proposed algorithm is shown. A computational result against real field data is reported and the resulting image is enhanced by the BV-like...
متن کاملIncoherent Synthetic Aperture Sonar Processing
This chapter investigates the incoherent approach applied in synthetic aperture sonar processing. The details of implementation are shown, and the technical properties of this technique are presented. Simulations are presented along the way for purposes of illustrations and comparisons. Discussions of the potential and limitation of this approach are made. All the simulations and analytical inv...
متن کاملBackprojection Autofocus for Synthetic Aperture Radar
In synthetic aperture radar (SAR), many adverse conditions may cause errors in the raw phase-history data. Autofocus methods are commonly used in SAR to mitigate the effects of these problems. Over the years, many types of autofocus have algorithms have been created, however, each has implicit assumptions restricting their use. The backprojection image formation algorithm places few restriction...
متن کاملStudy of the Local Backprojection Algorithm for Image Formation in Ultra Wideband Synthetic Aperture Radar
The purpose of this thesis project is to study and evaluate a UWB Synthetic Aperture Radar (SAR) data image formation algorithm, that was previously less familiar and, that has recently got much attention in this field. Certain properties of it made it acquire a status in radar signal processing branch. This is a fast time-domain algorithm named Local Backprojection (LBP). The LBP algorithm has...
