Basic Electromagnetic Compatibility Equation for Radio Communication Systems on Board Military Ships

In order to establish the state of electromagnetic compatibility (EMC) of naval systems, a special place is to obtain the EMC of radio communications systems on board military ships. This is a special challenge for any specialist in the domain both due to the particularly high density of technical means that are available on board military ships, and the fact that radio communication systems can be both sources of disturbance and victims. In obtaining the EMC of the systems, the inter and intrasystem disturbances must be identified and analysed. In order to fulfil the missions of combat, search and rescue and more recently, maritime surveillance and interception of boats with emigrants or refugees, military ships are constituted in naval groups. Such a group often includes ships under different flags, which are equipped with equipment and equipment from different suppliers and from different generations. In this sense, the entire naval grouping must be considered as a system, and the success of the mission may depend on the EMC's provision of the entire system.In the present paper, the authors present an algorithm for calculating the interference margins, necessary to obtain the EMC of a communications system related to a naval grouping starting from the basic EMC equation. The authors develop the EMC equation for radio communication systems aboard military ships.
