Sigma KEE - GuidedMissile

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)
Parents Missile A Projectile which is propelled by a rocket and contains a Bomb.
Children AAMAn air-to-air missile (AAM) is a guided missile fired from an aircraft for the purpose of destroying another aircraft. It is typically powered by one or more rocket motors, usually solid fuelled but sometimes liquid fuelled. (from Wikipedia)
 BeamRidingGMissileBeam-riding guidance leads a missile to its target by means of radar or a laser beam. It is one of the simplest forms of radar or laser guidance. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted in a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank. Then, the missile is launched and at some point after launch is gathered by the radar or laser beam when it flies into it. From this stage onwards, the missile attempts to keep itself inside the beam, while the aiming station keeps the beam pointing at the target. The missile, controlled by a computer inside it, rides the beam to the target. The aiming station can also use the radar returns of the beam bouncing off the target to track it, or it can be tracked optically or by some other means. (from Wikipedia)
 InfraRedGMissileA 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.
