Izraelci rade na projektu eliminisanja odraza vozila posmatrano u IC spektru. Znaci da bi FLIR na vozilima i letelicama postao beskoristan.

Citat:Israel’s thermal stealth innovator Eltics unveiled today a short video depicting the results of recent tests where large thermal panels installed on a Land Rover Defender vehicle managed to eliminate the vehicle’s signature, totally masking the vehicle from the thermal sight’s display.

Following a recent investment refuelling the start-up company, Eltics embarked on the development and testing of a full scale prototype of the Black-Fox active – adaptive – multi-spectral stealth system, to be able to mask a complete vehicle (both sides, front and rear). The system employs a thermal camera that samples the background view and a system processor and controller that recreates the necessary effects on the panels, blending the protected object into the background.

The company already raised 2.5 million in funding and plans to attract additional 5 million in the near future, enabling it to pursue the next stage – building and testing a full scale thermal suite in an operational test of the stealth technology. The compamy has embarked on a cooperative development with IMI, with the two companies joining forces in offering thermal adaptive signature management technology with IMI’s hybrid-reactive armor modules. The new combined module designated ‘Invisible Reactive Armor Protection’ (IRAP) will be designed to match a wide range of armored fighting vehicles.

By managing the heat distribution of the panels, the Black Fox system depicts a displayed across the panels, deceiving enemy sensors, therefore, making target identification, acquisition and tracking virtually impossible.
According to Ronen Meir Eltics CEO, the current system is capable of supporting an area 80 square meters of panels. This area will be sufficient to cover a large vehicle, on all sides. This installation will also employ specially designed windows that also minimize noticeable changes in thermal emissions, caused by the cooler transparent areas. The current system covers the entire infrared range, addressing thermal sensors operating in the both 3-5 and 8-12 micron wavelengths.


According to Meir, the company has also tested another function of the system – its ability to change pattern, depicting a different thermal silhouette. This function enables a ‘Black Fox’ equipped tank to ‘look like’ a truck, jeep or APC, or an air defense vehicle or missile launcher to look like an ordinary truck. These functions have significant implications in denying intelligence gathering by the enemy, by totally eliminating potential targets or misleading the enemy to regard such targets as ‘lower priority’ objects. In addition to denying enemy identification by thermal observation, Black Fox is also capable of deceiving or disrupting defending forces from being tracked or engaged by heat or Imaging Infra-red seekers.

Ovo u rezimu zadejstvovanja snaga i maskiranja nije nikakav problem realizacije, klimatizovani plast, koji bi radio po principu sredina -10 stepeni, i imao bi nisku cenu proizvodnje.

Dok u borbenim uslovima, klimatizovane oplate, npr na tenkovima bi bile jako slozene, dok na OT bi bile vise nego pozeljne, jer bi davale i dodatnu zastitu.

Drugi nacin da se ovo realizuje je koriscenje oplatnog materijala koji isijava u drugim spektrima, a neverujem da bi iko oklopljavao vozila plutom Smile

A shta che mo sa izduvnim gasovima.

A termovizija detektuje razliku u delovima od stepena.

Termovizija ne moze da detektuje zagrejani gas! moze samo u slucaju da on sadrzi dosta zagrejanih cvrstih cestica! U izduvnim gasovima (posebno benzinskih motora) ne mora da ih ima u velikim kolicinama

Ovo je stariji snimak kako bi to trebalo da funkcionise

Čekajte,kako ovo zapravo radi,na kom principu?

Na principu koji sam i ja izmislio za nekih 5 sekundi kad sam se jednom pitao kako da se armira i istovremeno maskira vozilo od termalnih sprava. Najosnovniji princip i prvi koji ti padne na pamet: stavi nesto izmedju sebe i osmatracke sprave sta ima neutralnu temperaturu i sa tim zakriva tebe koji si vruc, u principu je to zid koji je umesto da se vozilo sakrije iza njega pricvrscen na vozilu i ono ga vozi sa sobom. Ono je odmaknuto od vozila tako da se toplota motora ne prenosi na te celicne ploce i vazduh ih hladi/drzi na istoj temperaturi kao i okolinu. Nisu se nesto proslavili ovim, cudim se da uopste neko obraca paznju na ovo...

Znači nešto poput klasične termo izolacije Razz

BAE Systems Conjures Up Invisibility Cloak
Citat:
Known as "Adaptiv", the patented technology is based on sheets of hexagonal 'pixels' that can change temperature very rapidly. On-board cameras pick up the background scenery and display that infra-red image on the vehicle, allowing even a moving tank to match its surroundings. Alternatively, it can mimic another vehicle or display identification tags, reducing the risk of fratricide.
