Modern heat-seeking missiles utilise imaging infrared (IIR), where the IR/UV sensor is a focal plane array which is able to produce an image in infra-red, much like the CCD in a digital camera. This requires much more signal processing but can be much more accurate and harder to fool with decoys. See more Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" … See more The three main materials used in the infrared sensor are lead(II) sulfide (PbS), indium antimonide (InSb) and mercury cadmium telluride (HgCdTe). Older sensors tend to use PbS, newer sensors tend to use InSb or HgCdTe. All perform better when cooled, as … See more Most infrared guided missiles have their seekers mounted on a gimbal. This allows the sensor to be pointed at the target when the missile is … See more • Infrared countermeasures • Directional Infrared Counter Measures • Infra-red search and track See more Early research The ability of certain substances to give off electrons when struck by infrared light had been discovered by the famous Indian polymath Jagadish Chandra Bose in 1901, who saw the effect in galena, known today as lead sulfide, PbS. … See more The detector in early seekers was barely directional, accepting light from a very wide field of view (FOV), perhaps 100 degrees across or more.

WebJul 28, 2014 · Combining the information from radar and IR sensors, a heat-seeking missile is able to pinpoint the target. “The tracking radar tracks the trajectories of the missile as … WebIn a DIRCM system, the energy source is mounted in a strategically-located movable laser turret that only functions in "active mode" when the aircraft's missile warning system warns of a missile launch. It then targets the missile's heat plume to accurately focus a pulsing IR beam at the missile's "seeker" and jam its IR tracking ability. WebMany HEAT-armed missiles today [when?] have two (or more) separate warheads (termed a tandem charge) to be more effective against reactive or multi-layered armor. The first, smaller warhead initiates the reactive armor, while the second (or other), larger warhead penetrates the armor below. chis program army
