Paper Abstract

Target discrimination and recognition are dependent on the understanding of the dynamic acoustic information processed by a given sonar array. Visualization of the true near-field acoustic energy distribution of an active sonar array would be of great value to the understanding of the effects of structural defects in the array and its interface to the water medium. Knowledge of the projected near-field acoustic energy would also enhance the analysis of returned signals for homing and target recognition. Holographic interferometry has presented itself as a viable and useful method for the realization of this type of information.
