- 1 - THERMALLY-EMISSIVE, WEAPONRY TARGET, TRAINING AID OR ARC DESIGNATOR STRUCTURE ABSTRACT OF THE DISCLOSURE A thermally-emissive structure which can be a weaponry target, training aid or arc designator structure, the structure having a high heat emissivity material, such as matt black paint, applied in areas which are to define a thermally-emissive target. The mark/space ratio of the image so produced is varied over the area where the high heat emissivity material is applied to achieve the desired thermal image. The structure is electrically-heated and includes a heating element in the form of a plastics film having an electrically-conductive metallic coating. The plastics film is joined to a carrier member which in turn is joined to a rigid backing member of a material with good thermal insulating properties. The high heat emissivity material is applied to the plastics film and when the electrically-conductive coating is heated, thermal emission is markedly greater where the high heat emissivity material has been applied. The front of the plastics film is covered with an insulating material which allows transmission of thermal radiation through it.
