A thermal decoy system contains electro-resistive fabric which warms the air within a polymer envelope transmissive to infrared radiation. The thermal decoy system thereby produces a thermal signature comparable to that of a human, which will preemptively trigger passive-infrared sensors, thereby neutralizing such sensors' capability to detect nearby persons.

Countermeasure simulating structures may include (a) a base and (b) one or more separated combustible tracks fixed to the base's surface. The combustible tracks may include thermite and/or other combustible material. The combustible tracks may be shaped to simulate countermeasure flares deployed by a vehicle (e.g., a jet). The countermeasure simulating structure may be incorporated into a countermeasure simulating system that includes (a) an infrared and/or optical sensing system (e.g., like those included in missiles) and (b) a simulator mount holding the countermeasure simulating structure. Countermeasures may be tested in such systems by: (a) arranging an infrared and/or optical sensing system to receive infrared energy and/or visible light emitted by the countermeasure simulating structure; (b) igniting the combustible material of the combustible track such that combustion of the combustible material moves along the combustible track; and (c) determining whether the infrared and/or optical sensing system tracks infrared energy and/or visible emitted by the combustion.

A method of identifying an object signature in an environment includes acquiring infrared information from the environment using a detection unit in order to obtain an infrared wavelength spectrum associated with the environment. The method further includes selecting three wavelength bands of the infrared wavelength spectrum using a filtering unit and detecting a presence of the three wavelength bands of the infrared wavelength spectrum in the environment by filtering the selected three wavelength bands using the filtering unit. The method further includes determining an intensity indicator for the three selected wavelength bands using a processing unit and classifying the object signature using the processing unit based on the determined intensity indicator in order to identify the object signature.

A thermal imaging target includes a heating insulation layer, a heat conduction layer, a flow guiding layer, a bottom layer, and a self-heating package; the heat conduction layer bonded to the bottom layer, and an opening formed at the top to form a pocket-shaped structure; the self-heating package placed in a pocket, and a self-heating material arranged in the self-heating package for generating heat; the flow guiding layer placed between the heat conduction layer and the bottom layer to form cross-connected heat dissipation channels for guiding the heat generated by the self-heating package to crisscross flow in the pocket; the heat insulation layer attached to an outer surface of the heat conduction layer; thermal conductivity of the heat insulation layer lower than that of the heat conduction layer, so that a temperature difference is formed between the heat conduction layer and the heat insulation layer during heat conduction.

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.
