Abstract:

This validation effort effectively demonstrates that the IEMCAP code can successfully predict the EMC performance characteristics of a modern Air Force weapon system. In this validation, using the F-15 aircraft as the measured baseline for comparison, the IEMCAP predicted the overall system compatibility, some isolated cases of interference, and the compatibility effectiveness of the subsequent fixes. Numerically, this means that for 353 coupling pairs in some three major coupling modes wire-to-wire, antenna-to-antenna, and antenna-to-wire, IEMCAP successfully predicted 303 cases of compatibility, 7 cases of interference, and the effectiveness of their subsequent fixes, and 43 Type I errors in which the code predicted interference when actual compatibility was present. There were no Type II errors in the analysis in which compatibility was predicted when interference was present. With this validated computerized analysis program, Air Force product divisions and their system contractors can facilitate the practical implementation of EMC design-to-cost at all stages of an Air Force systems life cycle with the attendant scheduling, testing, and cost benefits. This effort supports technical program objective CCC survivability TPO 6RIC. Author
