Assessment methodology for radio frequency effects (RFE)

Abstract

The concept of radio frequency interference (RFI) is expanded to include RF damage or radiofrequency effects (RFEs). An assessment methodology was developed to predict the RF power density incident on a system that would cause upset or damage to the system electronics. This RFE assessment methodology is based on a modified version of the methodology used for electromagnetic pulse assessments. In the general assessment methodology for a system with a single entry path and critical component, the system under investigation is surveyed to identify the critical components and candidate RF entry ports. These areas are characterized in detail. The external power density that defines the susceptibility threshold of the system is determined. The methodology presents the results as a probability of system upset or damage (failure probability) as a function of incident RF power density.<>
