Reduced wavenumber synthetic aperture

The Journal of the Acoustical Society of America, 1997
Underwater acoustic imaging applications such as mine counter measures and sidescan seafloor surveys would benefit from an operational synthetic aperture sonar system. While the potential of high-resolution synthetic aperture (SA) sonar designs to provide unprecedented detection and discrimination performance is clear, the real-world issues of residual

Large-Wavenumber Fourier Imaging

2001
In Chapter 1 we discussed the historical aspects of migration. In that context, migration was viewed as the back propagation of the recorded data to its “correct” position on the image. This view was modified in Chapter 2 and 3, where we encouraged the reader to view this process as being the solution of an inverse problem.
