Underwater Vertical Electric Field Detection

In Phase II of this effort, Information Systems Laboratories, Inc. (ISL) will team with ERAPSCO to develop a low-cost underwater sensor capable of collecting both the horizontal and vertical components of electric field signals. ISL is a recognized leader in the development of undersea electromagnetic sensors and signal processing. ERAPSCO is a joint venture of USSI and Sparton, the world''s leading sonobuoy manufacturers. In Phase II, the data to be collected using existing sensors during the Phase I Option will be analyzed to validate the models developed in Phase I and for prototype system development. As part of the Phase II effort, a prototype three-axis E-field sensor buoy that is compatible with A-size buoy containers will be designed, fabricated, and tested. Additional data sets will be collected to optimize signal processing algorithms for E-field signal detection and localization and to validate system performance, models, and operation. The results of these tests will use to guide the design for an advanced engineering prototype of a compact E-field sensor package with the support of ERAPSCO.
