Below Decks Electromagnetic Survey Study - Phase 1

摘要

This report contains the results of the Phase 1 effort of the Below Decks Electromagnetic Environmental (EME) Study for United States Navy Ships. In this effort a description of how the below decks electromagnetic environment is affecting various shipboard systems, especially on the newer classes of ships, is discussed. Present specifications and their application have been inadequate in dealing with the problems created by the environment. A model has been developed to describe the below decks environment from HF transmit antennas. The prediction results of the model are compared to measured data from the FFG-7 class. Measurement techniques for collecting data on the FFG-7 and DD-963 class along with a task plan for a Phase 2 effort has been developed and is presented. A test plan for shipboard measurements is also presented. (Author)
