Theoretical Time Resolution of Sound Energy Returns from a Target in the First and Second LORAD Zones.

Abstract

In connection with a report on underwater sound propagation, several studies were made of the relative travel-time required for refracted rays of sound from a 50-foot source to reach a given point receiver. These follow at least four possible paths. The phase differences of such arrivals were studied over the range of the first zone for a 50-foot source and a 100-foot receiver. This led to a further study, the results of which are presented here in a technical memorandum as being perhaps timely to investigations in signal processing for LORAD and in neighboring fields.
