Digital C4I Interoperability: The EM Protection Issue
Abstract
In this paper, a unified protection methodology is applied to a digital mobile C4I platform subjected to several human-generated and nature-generated EM environments and effects. The unclassified values for self-induced electromagnetic interference (EMI), EM radiation (EMR), electrostatic discharge (ESD), near-strike lightning, and high-altitude EM pulse (HEMP) came from MIL-STD-464 and several commercial standards. By applying this methodology the EM protection requirements were estimated to be 70 dB enclosure port protection for frequencies between 100 MHz and 5 GHz, and 80 dB penetration port protection on the phone line for frequencies dependent upon the length of the phone line used. This EM protection strategy is both useful and cost effective to coalition forces, since validation testing and maintenance/surveillance testing to meet international standards reduce to simple, low-cost shield and penetration protection tests that can be conducted anywhere, even with the system operating. The application of this protection approach in the original system circuit design significantly reduces the number of breadboard and brassboard tests. Such protection also allows component replacement within the barrier, once the new component immunity level has been measured.
