Investigation of a Quasi-Holographic Synthetic-Aperture Acoustical Imaging System.
Abstract
A side-looking sonar system which uses coherent electrical processing is investigated. Such a system produces a quasi-hologram of the reflected sound field which may be subsequently imaged to give a visual presentation of the insonified region. An actual working laboratory system is constructed and several quasi-holograms are depicted in the Data and Results section. Imaging is not completed, however, an optical processing arrangement to accomplish this task is presented. (Author)
