Multipass and Nonconcentric Target Circular Synthetic Aperture Sonar (CSAS)

Abstract

In SERDP project MR-2439 research was conducted to enable the in-situ measurement of the aspect and grazing angle dependent scattering response of unexploded ordnance (UXO), clutter, and science targets by conducting circular scans at different heights around identified concentric and non-concentric (i.e. off-center) targets. Methods were developed for coherently fusing the information from all circular scans to generate three-dimensional data products describing spatial reflectivity and impulse response of targets. Showing that these three dimensional (3D) data products could be sampled in the 3D wavenumber spectrum to generate a series of two dimensional (2D)random orientation realizations that have use for target recognition training and/or testing was an additional objective.
