An Improved Method for Approximating Depth and Position of Bottomed Modules.

摘要

A single series of shots is fired in a circle with a known diameter around some fixed reference point. It is preferable (but not absolutely necessary) that the circle be located so that the module is somewhere within it. The time delay for each shot position is measured. These are then converted into slant ranges and from these the position and depth of the module may be calculated.
