Shielding Effectiveness Measurements on Hardened, Transportable Facilities Using Transmission-Line Techniques

摘要

As pant of science and engineering efforts between U.S. and French personnel, a testbed was devised that demonstrated an alternative approach to evaluating radio-frequency doors. The methods used multiwire transmission lines of the type generally used to perform radiated immunity measurements. Analysis of the results has provided a unique method of determining the electromagnetic susceptibility and long-term hardness-maintenance/ hardness-surveillance status of critical command, control, communications, computers, and intelligence (C4I) facilities.
