Antenna co-site performance analysis for complex systems using Feature Selective Validation

Abstract

This paper illustrates the application of a new technique called the Feature Selective Validation (FSV) to assist in an antenna siting problem for a complex aircraft vehicle. The FSV is based on the IEEE 1597.1 Standard for the Validation of CEM Computer Modeling and Simulations. In practice, various antenna configurations must be analyzed in order to localize antenna placement to meet both performance and co-site EMC requirements. The results of a limited sensitivity analysis are presented using canonical models of an airframe wing structure to identify the best placement of a simple dipole. The FSV facilitates comparisons between sets of electromagnetic observables to determine the impact of antenna placements. The results of hybrid MoM/UTD simulations at high frequencies approaching 1 GHz are compared to validate results and demonstrate the efficacy of the FSV method, which can be used to conduct sensitivity analyses for virtually any co-site problem.
