Development of a Maritime Electronic Warfare and Sensor Systems EMI Mathematical Assessment Capability

Electronic warfare and sensor (EW&S) systems have to meet their operational capability in a maritime environment. However, with the ever increasing number of EW&S systems being fitted onboard maritime platforms [1] and the reality that maritime platforms are being required to operate jointly, the likelihood of adverse electromagnetic interference (EMI) between EW&S systems is prominent. Investigating EW&S systems' electromagnetic compatibility (EMC) can be an extremely complex problem [2]. If EW&S system EMC is not addressed and managed in a correct procedure, the solutions to minimise EMI problems can be expensive and more importantly can affect the operational capability of the systems, [2] and [3]. What has been recommended, by many in the EMC community (e.g. [1], [2], [3] and [4]), as a means of managing the complexity of systems' electromagnetic interference and/or electromagnetic compatibility (EMI/EMC) problems, is that the EMI/EMC must be assessed at the planning, designing and development, installation, and/or operation of electrical and electronic equipments stages, each governed by an EMI Control Plan.
