  2. Infrared homing - Wikipedia

    en.wikipedia.org/wiki/Infrared_homing

    Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. [1] Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies.

  3. Flare (countermeasure) - Wikipedia

    en.wikipedia.org/wiki/Flare_(countermeasure)

    A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.

  4. Directional Infrared Counter Measures - Wikipedia

    en.wikipedia.org/wiki/Directional_Infrared...

    Directional Infrared Counter Measures (DIRCM) are a class of anti-missile systems produced to protect aircraft from infrared homing missiles, primarily MANPADS and similar simple systems. Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional.

  5. Indium antimonide - Wikipedia

    en.wikipedia.org/wiki/Indium_antimonide

    Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb). It is a narrow-gap semiconductor material from the III-V group used in infrared detectors, including thermal imaging cameras, FLIR systems, infrared homing missile guidance systems, and in infrared astronomy.

  6. R-73 (missile) - Wikipedia

    en.wikipedia.org/wiki/R-73_(missile)

    The R-73 is an infrared homing (heat-seeking) missile with a sensitive, cryogenic cooled seeker with a substantial "off-boresight" capability: the seeker can detect targets up to 40° off the missile's centerline. [8] It can be targeted by a helmet-mounted sight (HMS) allowing pilots to designate targets by looking at them. Minimum engagement ...

  7. Infrared - Wikipedia

    en.wikipedia.org/wiki/Infrared

    Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers" since infrared (IR) is just below the visible spectrum of ...
