Abstract
A method for determining the likely range and depth of an acoustically radiating source in which characteristics are used from hypothetical ranges and depths. A received sonar signal is compared with modeled ranges and depths. The correlation between the received signal characteristics and the modeled characteristics gives the likely range and depth. In a preferred embodiment this is presented as a contour plot.
