Adaptiv is an active camouflage technology developed by BAE Systems AB to protect military vehicles from detection by far infrared night vision devices, providing infrared stealth. It consists of an array of hexagonal Peltier plates which can be rapidly heated and cooled to form any desired image, such as of the natural background or of a non-target object. Its goal is to develop stealth ground vehicles.
In 2011, BAE Systems announced their Adaptiv infrared military camouflage technology, likening it to "a thermal TV screen". [2] It uses about 1000 hexagonal panels to cover the sides of an armoured vehicle such as a tank or personnel carrier. Infrared cameras continuously gather thermal images of the vehicle's surroundings. The Peltier plate panels are rapidly heated and cooled to match either the temperature of the background, such as a forest, or one of the objects in the thermal cloaking system's "library" such as a truck, car or large rock. The system is able to gather and display thermal images while the vehicle is moving. The result is to "cloak" the vehicle from detection by heat-detecting night vision devices (thermographic camera systems). [3] [4]
For crypsis, the panels can display an infrared image of the vehicle's background; this can be updated as the vehicle moves. For mimesis, an image of a chosen object, such as a car, can be retrieved from Adaptiv's library and superimposed on the background. The illustration shows Adaptiv mimicking a four-wheel drive car, using part of the panel, while the rest of the panel is cryptic, imitating the natural background. [3] [4] The technology is said to reduce the range at which a vehicle would be detected to less than 500 metres. [5]
The panels forming Adaptiv's pixels are hexagons approximately 5.5 inches (14 cm) wide. [3] They are robust, contributing to the armour of the vehicle that carries them. [3] The system allows its operator to "grab" a thermal image from a vehicle or other object for display. [6]
Adaptiv was developed by BAE Systems AB's survivability programme at Örnsköldsvik, Sweden, initially for Combat Vehicle 90 infantry fighting vehicles. [4] The company has developed a lighter version which has been tested on helicopters. [7] [2] A version for ships could in principle use larger panels. [4] A somewhat similar system was prototyped to an early stage by the Israeli company Eltics in 2010. [8]
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.
A cloaking device is a hypothetical or fictional stealth technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years.
Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible. The phenomenon is studied by physics and perceptual psychology.
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.
Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range. Humans have poor night vision compared to many animals such as cats, dogs, foxes and rabbits, in part because the human eye lacks a tapetum lucidum, tissue behind the retina that reflects light back through the retina thus increasing the light available to the photoreceptors.
Stealth technology, also termed low observable technology, is a sub-discipline of military tactics and passive and active electronic countermeasures, which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible to radar, infrared, sonar and other detection methods. It corresponds to military camouflage for these parts of the electromagnetic spectrum.
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, thermography is particularly useful to the military and other users of surveillance cameras.
Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection.
Military camouflage is the use of camouflage by an armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress, either to conceal it from observation (crypsis), or to make it appear as something else (mimicry). The French slang word camouflage came into common English usage during World War I when the concept of visual deception developed into an essential part of modern military tactics. In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or enable surprise. As such, military camouflage is a form of military deception in addition to cultural functions such as political identification.
Stealth helicopters are helicopters that incorporate stealth technology to decrease an enemy's detection ability. There are a diverse range of technologies used to achieve this decreased detectability; these have largely involved the reduction of several different signatures typically generated by a rotorcraft, including those of noise, radar, and infrared.
Electro-optical MASINT is a subdiscipline of Measurement and Signature Intelligence, (MASINT) and refers to intelligence gathering activities which bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), or Human Intelligence (HUMINT).
The AN/VAS-5B(V) Driver's Vision Enhancer (DVE) is a passive thermal imaging system used to enhance a driver's viewing capabilities while operating during degraded visual conditions, such as darkness, fog, smoke or dust.
Infrared signature, as used by defense scientists and the military, is the appearance of objects to infrared sensors. An infrared signature depends on many factors, including the shape and size of the object, temperature, and emissivity, reflection of external sources from the object's surface, the background against which it is viewed and the waveband of the detecting sensor. As such there is no all-encompassing definition of infrared signature nor any trivial means of measuring it. For example, the infrared signature of a truck viewed against a field will vary significantly with changing weather, time of day and engine loading.
ALAS is a Serbian long-range multipurpose wire guided missile system developed by the private company EdePro and the state-owned Yugoimport SDPR. The ALAS missile system was developed primarily for missions against tanks, armored vehicles, fortifications, command posts, low-flying helicopters, coastal ships, industrial facilities and bridges. It can be deployed by any suitable platform including helicopters, armored vehicles, small ships and infantry. The guidance system is based on video/infrared technology, with the missile connected to the launcher by a fiber-optic cable. The ALAS flies at low altitude and has small radar and infrared (heat) signatures due to using a turbofan motor instead of a turbojet. In recent years, the ALAS platform has found a secondary use as a UAV.
An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles. The technology was first introduced in the year 2000 on the Cadillac Deville. This technology is based on the night vision devices (NVD), which generally denotes any electronically enhanced optical devices operate in three modes: image enhancement, thermal imaging, and active illumination. The automotive night vision system is a combination of NVDs such as infrared cameras, GPS, Lidar, and Radar, among others to sense and detect objects.
Nakidka is a Russian radar-absorbent material (RAM) camouflage that "eliminates the use of precision-guided weapons". Nakidka reduces the infrared, thermal, and radar band signatures of an object. It can be mounted on armored fighting vehicles, field fortifications, command posts, permanent air and vehicle sheds, and ammunition and fuel depots by infantry with no special equipment.
This is a list of infrared topics.
Multi-spectral camouflage is the use of counter-surveillance techniques to conceal objects from detection across several parts of the electromagnetic spectrum at the same time. While traditional military camouflage attempts to hide an object in the visible spectrum, multi-spectral camouflage also tries to simultaneously hide objects from detection methods such as infrared, radar, and millimetre-wave radar imaging.
An enhanced flight vision system is an airborne system which provides an image of the scene and displays it to the pilot, in order to provide an image in which the scene and objects in it can be better detected. In other words, an EFVS is a system which provides the pilot with an image which is better than unaided human vision. An EFVS includes imaging sensors such as a color camera, infrared camera or radar, and typically a display for the pilot, which can be a head-mounted display or head-up display. An EFVS may be combined with a synthetic vision system to create a combined vision system.
Challenger 3 (CR3) is a planned British main battle tank in development for the British Army. It will be produced by the conversion of existing Challenger 2 tanks by the British/German Rheinmetall BAE Systems Land joint venture.
This helicopter is covered in ADAPTIV hexagonal panels. The ADAPTIV system has a library of images it can display, though for a helicopter the best option is to match the surrounding thermal conditions.
