AbstractPhysics-based modeling and simulation tools for predicting electromagnetic interference (EMI) and vulnerability (EMV) between RF systems are playing an increasingly important role in system level performance predictions. In order to accurately capture all of the complexity associated with RF systems on a modern military platform, very sophisticated multi-physics simulators using models of multiple levels of fidelity are required. In order to instill a high level of confidence in the tool's predictive capability, analysis improvements based on lessons learned in a complete and careful measurement-based validation on real-world systems is a must. Under the proposed project Delcross Technologies and its team will undertake a comprehensive measurement-based validation of its Electromagnetic Interference Toolkit (EMIT) based at first on a canonical test system and then on a complete modern airborne system involving multiple RF systems. Based on the benchmarking against these systems, enhancements to EMIT's multi-physics analysis engines and field-circuit interaction module will be identified and implemented. The methodologies used for creating models of RF components to be used by the simulator will also be refined based on the measurements. The ultimate outcome of this project will be an improved and fully-validated multi-fidelity/multi-physics simulation tool for the analysis of cosite and intersystem EMI.
