Shipboard EMI/EMC Test Report for the Reduced Ships-Crew by Virtual Presence (RSVP) Advanced Technology Demonstration (ATD)

摘要

EMI/EMC testing was conducted on board the USS Normandy (CG-60), a Ticonderoga Class Aegis Cruiser in early April of 1999. The tests were made to determine a typical electromagnetic operating environment for the RSVP RF communications System and to perform propagation measurements in the proposed 2. 4 GHz ISM band. The scope of the testing included measurements of the electromagnetic environment from 10 KHz to 3 GHz in three different spaces aboard the ship, and 2.4 GHz propagation measurements in those spaces. The spaces chosen were Main Engine Room 2, Auxiliary Machinery Room 1 and Engineering Crew Quarters. Of particular interest for the EM measurements was the band at 2.4 GHz and those surrounding 100 MHz and 10.7 MHz the proposed first and second intermediate frequencies (IFs) for the RSVP receiver. While the testing revealed no serious problems, it must be remembered that these measurements are only a snapshot in time aboard a single ship. Testing on board different ships may reveal significantly different results.
