Investigatiaon on the far-field characteristic of radar radiant source in ship fleet

Reliable and accurate propagation path loss prediction between radar radiant sources and susceptive equipments necessitates a good understanding of electromagnetic wave scattering in the presence of inhomogeneous atmosphere near sea, and this is one of the major issues in ship fleet electromagnetic compatibility literature. For sake of this reason to solving the far field of the radar radiant source inner the ship fleets, this paper proposed a wide-ranging applicability method to compute the far field of the radar on the Shipboard. These methods take some factors into attention, such as the reflectivity of the rough sea surface, the multipath loss, and globe curvature, and can compute the magnitude of the far field of the radar mounted on shipboard. The computed model of the far field of the radar in ship fleet can provide electromagnetic environments parameters, further, can be used into the electromagnetic compatibility analysis of the whole ship fleet. Then the computed model of the far field of the radar in ship fleet is certificated by the measurements, and is used to investigate the far field characteristic of radar radiant source in ship fleet.
