Paper Abstract

In an underwater acoustic holographic imaging system, relative motion between the imaged objects and the recording plane may destroy the image. If the relative motion is known, the recorded hologram may be corrected so that the degraded image can be recovered. The system used in the study consisted of a linear scanning receiving array and a perpendicularly-oriented cylindrical insonifier. The signals detected by each receiving element are com-pared with electronic reference signals, thus generating in-phase and quadrature components. In this paper, uniform relative motion of translation between an object and the recording plane is computer simulated. Both horizontal and vertical motions are considered. An algo-rithm for image restoration and reconstruction is then applied to these data. Three-dimen-sional perspective plots are used to illustrate the results.
