EMIT represents a revolutionary advance in RFI analysis providing a host of powerful features for usability, computational effi ciency and results diagnostics. EMIT provides a framework for managing RF system performance data, simulating cosite and coexistence RFI eff ects, and mitigating RFI issues, resulting in a complete model maintainable over the life of a multi-RF system platform or vehicle. EMIT takes a unique multi-fi delity approach to predicting RF cosite/coexistence interference to provide rapid identifi cation and “root-cause” analysis of RFI issues in complex RF environments.
