Research on Evaluation Method of Ship EMC Based on Multi-layer Coupling Network

This paper proposes the method based on multi-layer coupled networks to evaluate ship electromagnetic compatibility (EMC). Firstly, based on the theory of multi-layer coupled network systems, the equipment and their transmission link that mainly influence the ship EMC are defined as the nodes and edges of the evaluation model; Secondly, the network layers of the different domain of the evaluation model are located, as well as the coupling methods between the layers are provided; Then, according to the characteristics of the multi-layer network model, the evaluation method of the influence of the key nodes on the ship’s EMC is given; Finally, the effectiveness of the evaluation method of ship EMC based on multi-layer coupled network is verified by analyzing several frequency using equipment on the ship. This method has certain reference significance and development prospects in the field of the evaluation of ship EMC.
