A method according to claim 20 wherein the array is fastened to the vessel structure by welding or by screw fastening to the structure.22. A method according to claim 20, wherein the vessel structure comprises any surface on the structure capable of reflecting a radar signal.23. A method according to claim 20, wherein the arrangement of elements on the vessel structure is such that the facets of the elements reflect the incident radar signal away from a threat direction.24. A method according to claim 20, wherein the array comprises a plurality of sheets capable of being joined together.25. A method for retrofitting an array to a vessel to reduce its radar signature, the array being as claimed in claim 1, the method including the step of fastening to surfaces of the vessel structure in sheet form one or more arrays comprising a plurality of uniformly shaped elements being triangular, polyhedral, pyramidal or prismatic in shape and having edges defining the boundary of the reflective surfaces being such that the faces and the edges are oblique to the direction of incident radar for a given range of incident directions, the arrangement being such that when fastened to surfaces of the vessel structure the reflective surfaces are oriented so as to coherently reflect an incident radar signal by up to about 30 degrees away from its direction of incidence for a given range of incident directions.26. A retrofitted vessel made by the method of claim 20.
