Propagation Loss Assessment of the BEARING STAKE Exercise

Abstract

The BEARING STAKE exercise was an acoustic measurement program that was conducted at five selected sites in the Northwest Indian Ocean during the period of January through May 1977. The major objective of BEARING STAKE was to collect acoustic data to determine the variability in the acoustic environment and to provide inputs to systems performance evaluation models. This report contains an overall assessment of the propagation loss data collected during BEARING STAKE at the following sites in the Northwest Indian Ocean: Site 1A/1B (Gulf of Oman), Sites 2 and 3 ( central Arabian Sea), Site 4 (western Somali Basin), and Site 5 (southern Arabian Sea). The BEARING STAKE exercise was successful in terms of collecting, analyzing, and interpreting acoustic data. The lesson learned from this exercise is that an acoustic measurement program, such as BEARING STAKE, should be conducted in ocean areas where the deployment of surveillance systems is being considered. Although theoretical models have been developed to predict the propagation losses for surveillance systems in specified locations, these predictions are only as good as the environmental acoustic inputs to the models.
