ABSTRACT:
A method is disclosed where acoustic pulses are used to calculate the velocity of the medium. The inventive aspect of the invention is that the acoustic velocity may be calculated without initially knowing the separation distance between the source and the distant receivers. The method utilizes established geometrical relationships which may be solved to produce the velocity. The velocity is often used to calculate the separation distances between the desired points.
