Surface-to-air missiles have again caught the world's attention after the crash of Malaysia Airlines flight MH17 in Ukraine. Developing accurate missile guidance systems has been a quest of military powers since World War II. To come up with the most lethal attack weapon, defence researchers around the world have experimented with myriad technologies ranging from heat-seekers or infrared IR sensors, radar systems and thermal imaging to laser.
Heat-seeking missiles have two major components. A radar system—which can either have a single or multiple radars—is stationed on the ground. On the top of that, the missile has a heat-seeking system, such as an infrared sensor, on its tip, which can identify infrared rays emitted by the targeted plane. Its coordinates change continuously. IR rays are electromagnetic radiations that are emitted depending upon the temperature of a particular object—the hotter the object, the stronger the infra red radiation.
Since the temperature at high altitudes, such as 32, ft, is ificantly low, radiations emitted by the target are immediately spotted by the missile. Combining the information from radar and IR sensors, a heat-seeking missile is able to pinpoint the target. Never miss a story! Stay connected and informed with Mint. Download our App Now!!
