红外导弹
A missile that is guided by infrared homing. Infra-red homing refers to a guidance system which uses the infra-red light emission from a target to track it. Missiles which use infra-red seeking are often referred to as heat-seekers. Infra-red (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and retain heat, and as such, are especially visible in the infra-red wavelengths of light compared to objects in the background.

Relationships      
Parents 导弹 Missiles that have the ability to maneuver through the air can be guided, and are known as guided missiles. These have three key system components: * tracking * guidance * flight A tracking system locates the missile's target. This can be either a human gunner aiming a sight on the target (remotely from the missile) or an automatic tracker. Automatic trackers use radiation emanating from the target or emitted from the launch platform and reflecting back to it from the target. Passive automatic trackers use the target's inherent radiation, usually heat or light, but missiles designed to attack Command & Control posts, aircraft or guided missiles may look for radio waves. Active automatic trackers rely on the target being illuminated by radiation. The target can be painted with light (sometimes infrared and/or laser) or radio waves (radar) which can be detected by the missile. The radiation for the painting can originate in the missile itself or may come from a remote station (for example, a hilltop gunner can illuminate a target with a laser device and this can be used to direct an air launched guided missile). A guidance system takes data from the missile's tracking system and flight system and computes a flight path for the missile designed to intercept the target. It produces commands for the flight system. The flight system causes the missile to maneuver. There are two main systems: vectored thrust (for missiles that are powered throughout the guidance phase of their flight) and aerodynamic maneuvering (wings, fins, canards, etc). There are some similarities between guided missiles and guided bombs. A guided bomb, dropped from an aircraft, is unpowered and uses aerodynamic fins for forward horizontal maneuvering while falling vertically. (from Wikipedia)
Children AG m65The AGM-65 Maverick is an air-to-surface tactical missile (ASM) designed for close air support, prohibition, and forceful prevention. It is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation, and fuel storage facilities. The AGM-65F (infrared targeting) used by the US Navy has an infrared guidance system optimized for ship tracking and a larger penetrating warhead than the shaped charge used by the US Marine Corps and the US Air Force (300 pounds (136 kg) vs 125 pounds (57 kg)). The AGM-65 has two types of warheads, one has a contact fuze in the nose, and the other has a heavyweight warhead with a delayed fuze, which penetrates the target with its kinetic energy before firing. The latter is most effective against large, hard targets. The propulsion system for both types is a solid-fuel rocket motor behind the warhead. (from Wikipedia)
 AI m9The AIM-9 Sidewinder is a heat-seeking, short-range, air-to-air missile carried by fighter aircraft and recently, certain gunship helicopters. It is named after the Sidewinder snake, which also detects its prey via body heat. The Sidewinder was the first truly effective air-to-air missile, widely imitated and copied. Its latest variants remain in active service with many air forces. (from Wikipedia)
