TV-like pictures, showing position and shape of underwater missile test items are obtained by using a directional-scanning sonar method. This report is a systems study made to investigate the problems of acoustical imaging within the broad concept of such an instrumentation device. It covers the interrelationship of absorption, bandwidth, information-theory limits, and beam theory for transducers and acoustical lenses.
