OCEANOGRAPHIC INSTRUMENTS AS A BASIS OF SUBMARINE DETECTION AND CLASSIFICATION SYSTEMS
Abstract
The transit of a submerged submarine subjects the ocean environment to many subtle changes. During the past several years specialized in situ oceanographic instrumentation has been designed to sense these physical, chemical, and biological modifications of the ocean. Laboratory research results show the many facets of the problem and the general usefulness of the ocean as a readymade complex easily changed by a transiting submarine. The submarine-generated energy transfers, acoustic and hydrodynamic, are detectable by simple optical instruments. The results of several field operations have demonstrated the performance of turbidimetric and colorimetric sensors used for wake sensing of a submerged submarine during recent field operations in the Florida Straits. Emphasis on submarine detection and classification systems suggests useful comparisons to conventional acoustic signal processing, where the ocean-environment noise for a given parameter, such as turbidity, is treated in terms of bandwidth, sampling time, resolution, detection, false-alarm probability, and signal-to-noise ratio.
