Depth Scaling of Underwater Explosion Source Levels

Abstract

A new method of depth scaling underwater explosion source levels is presented. The method involves modification of the negative phases of the explosion pressure-time history. The method is shown to be accurate for depth change of an order of magnitude, and frequencies greater than twice the bubble pulse fundamental frequency. This technique is most easily applied to digital data, and is useful in situations where only a minimal investment of time and effort is possible. Scaling by means of a constant time (or frequency) scale factor is shown to be inadequate for large depth changes.
