Co-existence of AESA (Active Electronically Scanned Array) radar and Electronic Warfare (EW) systems on board of a military ship

In the context of the design of modern military ships, a significant issue is the Topside (or integrated mast) design i.e. the configuration of the equipment, sensors and actuators that constitute the Naval Combat System (SdC). The arrangement of the sensors affects the performance of the radio-frequency devices installed on board and therefore their effective coexistence. This paper reports on a simplified yet effective study to minimize the negative impact of a radar e.m radiation on an Electronic Warfare (EW) system when the two equipment are positioned on the same mast of a ship.
