Statistical evaluation and comparison of radiated emission standards

To evaluate a system or platform on its electromagnetic compatibility generally involves the application of several EMC standards. In order to compare applicable standards, one needs a common denominator as a basis. In this study, EMC norms for electromagnetic radiation are assessed statistically. A framework describing stochastic electromagnetic fields is applied and at the hand of the examples of military (MIL) and international electrotechnical commission (IEC) standards further developed for this purpose. The formalism not only evaluates such requirements but also enables the comparison of different standards in a probabilistic way. First illustrative results are presented. Frequency bands are identified for which IEC complying equipment exceeds the MIL standard with high probability.
