Multispectral camouflage systems, apparatuses, and methods describes herein may include an assembled array of one or more discrete camouflage units, wherein each of the one or more discrete camouflage units includes a composite material having at least one predetermined structurally related property and at least one predetermined camouflage-related property, and wherein each of the one or more discrete camouflage units is joined to one or more neighboring unit to provide a laterally positioned camouflage cover configured to conceal an object from visible detection, infrared detection, thermal imaging, and radar detection.

Camouflage coating systems, apparatuses, and methods described herein may include a coating deposited and bonded to a region of an external surface of an object to be camouflaged. The coating may include a plurality of stacked material arrangements deposited and bonded sequentially onto the region of the external surface and arranged to define a laterally distributed plurality of independent camouflage profiles. The coating may be configured to adjust coating emissivity at visual and IR wavelengths and to block or adjust infrared (IR) emitted by the object, thereby concealing the region of the external surface of the object from detection by a detection method in the visual, infrared, and electromagnetic regimes.

Systems, methods and apparatus are described for a HERF weapon that may emit high-energy radio waves at a target based on locational information and a frequency associated with the target. The HERF weapon may receive the frequency and locational information from a sensing system. The HERF weapon may emit a high energy pulse toward the target and on the frequency associated with the target to disable or destroy the target without affecting nearby devices. The HERF weapon may allow the user to avoid detection by using a frequency that corresponds to the target's operating frequency.

The present invention relates to an infrared stealth element using a dual band perfect absorption metamaterial. The infrared stealth element includes: a first metal layer; an insulator layer formed on an upper part of the first metal layer; and a second metal layer formed on an upper part of the insulator layer. The second metal layer includes at least one among a metal ring and a metal dot.

An underwater acoustic deception system deceives a sensor installed on a threat existing in or on water by acoustic effect in order to protect ships from the threat. The underwater acoustic deception system is provided with a control device, a laser oscillator and emission optical system. The control device determines a focusing position to focus a laser beam (50) in water in order to generate bubbles (70) at a desired position with a desired scale and emission parameters of the laser beam (50). The laser oscillator generates the laser beam (50) configured to focus in water and generate bubbles. The emission optical system emits the generated laser beam (50) to the focusing position. The underwater acoustic deception system deceives an arbitrary sensor existing in the water by acoustic effect of the bubbles (70) on the surroundings.

A site-specific photographic camouflage arrangement and method for making the same are provided. The site-specific photographic camouflage arrangement includes a digital photographic image and distorting disruptive patterns placed on the digital photographic image to create visual confusion to disguise the recognizable form of a camouflaged object by breaking up its outline.
