It is herein proposed a novel multi-spectral artificial target device for producing a deceptive thermal and radar signature of an object. The device features a multi-layer structure with a substrate and a functional thermal signal layer, which is provided directly or indirectly on the substrate. The substrate is made of pliable material which is capable of being shaped on a frame. The thermal signal layer includes electrically conductive material such arranged to form an array of independently controlled thermal elements for outputting a thermal signal, which is observable in the infra-red spectrum, upon exposure to a control voltage. The multi-layer structure further includes a functional radar signal layer, which is provided directly or indirectly onto the substrate. The radar signal layer outputs a radar response signal, which is observable in the radio frequency spectrum, upon exposure to an external radar stimulus or excitation.
