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.

A shooting target, including an air blower, a fabric envelope assembled on the air blower, for being inflatable thereby, and an electric current meter, for measuring electric current flowing through the air blower, thereby allowing indicating a bullet shot on the fabric envelope while being inflated, upon determining a change in the measured electric current.

The invention relates to a decoy (3) for protecting a fast aircraft (1) against an incoming threat (2), wherein said decoy is non-driven. The decoy (3) has a squib (6) on one end and a molded body (11) on the opening side. If the decoy (3) has an active material container (8), the squib (6) can be attached to the end side thereof and the molded body (11) attached to the opening side thereof. The squib (6) contains a propellant, which is converted into a drive energy. The molded body (11) is heavier than the decoy (3) without the molded body (11) and has the task of preventing the separating of the molded body (3) to the rear. In addition, the molded body (11) should be at least 1.0-1.5 times heavier than the decoy itself. Advantageously, however, the molded body (11) is twice as heavy.

We disclose herein an infra-red (IR) device comprising a substrate comprising an etched cavity portion and a substrate portion; a dielectric layer disposed on the substrate. The dielectric layer comprises a dielectric membrane which is adjacent, or directly above, or below the etched cavity portion of the substrate. The device further comprises a reflective layer on or in or above or below the dielectric membrane to enhance emission or absorption of infrared light at one or more wavelengths.
