  • http://en.wikipedia.org/wiki/Infrared_homing ...this should help you :-)
  • There are 4 main methods that missiles use to track their targets. 1) Radar --- The missile detects radar waves reflected from the target. The radar signal is usually generated from elsewhere (an aircraft, ship or ground station). Some missiles are designed to specifically home in on the radar signals generated by these sources and destroy them. 2) Infrared - The missile detects and homes in on the heat 'signature' of the target. These can sometimes be fooled by bright heat sources, such as the Sun or countermeasure flares. 3) Laser designation - The missile tracks the reflected light of a laser beam that has been pointed at a target. This is used more with 'smart bombs', which don't have a rocket motor but do have a guidance system. 4) GPS pre-programming - The missile is programmed to go to a particular set of coordinates. During its flight, the missile communicates with GPS satellites to verify and correct its course. This is how most 'cruise missiles' are guided. I hope this helps. . . .
