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 ...
These jamming systems transmit either a high-powered IR carrier signal to blind the IR detector of the incoming IR missile or transmit a lower-powered IR carrier signal modulated with a modulating signal to confuse the IR detector of the incoming missile. As infrared missiles are increasingly cheap and simple, they have been increasingly dangerous.
Protecting aircraft against IR guided missiles depends in most cases firstly on reliable detection and warning of missiles and secondly on applying effective ECM. An exception to this are omni-directional IR jammers which do not make use of missile warning at all, as they simply radiate modulated IR energy for as long as they are switched on.
An ALQ-144 jammer mounted on an OV-10 Bronco.. The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infrared guided missile countermeasure devices ().They were developed by Sanders Associates in the 1970s to counter the threat of infrared guided surface-to-air missiles like the 9K32 Strela-2.
Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional. This results in the missile seeker receiving relatively little IR energy due to the inverse square law. DIRCM systems instead aim their IR output directly at the missile using some source of tracking ...

Common examples of these weapons include the BGM-71 TOW wire-guided anti-tank guided missile (ATGM) and the Rapier radio-command surface-to-air missile (SAM). Another class of SACLOS weapons is based on the beam riding principle. In this case, a signal is sent from the operator's sights toward the target. The signal is generally radio or a ...
