Prediction of Topside Electromagnetic Compatibility in Concept-Phase Ship Design

An approach for the prediction of topside electromagnetic compatibility in the concept phase of naval ship design is proposed and demonstrated. The approach was developed by utilizing the commercially available numerical computational package, Computer Simulation Technology, to assess the electromagnetic environment of a Royal Navy Type 22 Batch II Frigate. A number of the results of such an assessment were validated using measurements on a 1:50 scale copper model of the Type 22 Batch II Frigate. The approach was then applied to a new concept phase design study for a Future Patrol Ship, produced by UK Ministry of Defence's Naval Design Partnership. This work is expected to be useful in assessing the severity of topside EMI, using numerical modeling and simulations, in Concept-Phase Ship Design.
