Source Ranging by a Single Array in a Multipath Ocean.

Abstract

The objective of this work was to develop a possible way of source ranging by a single array in a multipath ocean and to indicate its limitations. It was shown that mean-square sound-level fluctuations for a single sensor in a random multipath environment are directly dependent on the source range. When this was applied to an array of sensors, the result showed that a single horizontal line array might track a moving source in a multipath ocean environment. This result would facilitate the inter-array communication problem for coherent multi-array processing (CMAP) tracking of submarines. It is recommended that this tracking method be further tested with even more suitable data.
