How does a seeker missile work?

The seeker does not track the target, but the missile, often aided by flares to provide a clean signal. The same guidance signals are generated and sent to the missile via thin wires or radio signals, guiding the missile into the center of the operator’s telescope.

How do missiles navigate?

Active homing uses a radar system on the missile to provide a guidance signal. Typically, electronics in the missile keep the radar pointed directly at the target, and the missile then looks at this “angle” of its own centerline to guide itself.

Do missiles spin in flight?

Spin they do, but not necessarily at the same speed as a bullet; nor for very long. In the case of rockets, the “spin” is really a roll program, and is part of the maneuver to get the rocket headed the way you want it to go. Thus we see it early after launch, but it frequently stops further along the flight path.

How does an RF seeker work?

The tracker makes use of an active radio frequency (rf) seeker (a radar mounted in the front of the missile) as main source of information about the target. Up until the point in time when the seeker starts delivering target data the missile is able to receive and process data sent to it over a data-link.

How does a missile guidance system work?

The guidance system in a missile can be compared to the human pilot of an airplane. As a pilot guides his plane to the landing field, the guidance system “sees” its target. If the target is far away or otherwise obscured, radio or radar beams can be used to locate it and direct the missile to it.

How do missiles spin?

Basically, a rolleron is a metal wheel with notches cut into it. As the missile speeds through the air, the air current spins the rolleron like a pinwheel. The rollerons on the rear wings help stabilize the missile in flight.

How do rockets spin?

In flight, the fins of the rocket produce aerodynamic forces. The torques cause the rocket to rotate. Most full scale rockets produce pitch or yaw motions by gimballing, or rotating, the exhaust nozzle. If the thrust vector is not alligned with the roll axis, it produces a torque about the center of gravity.

How do laser guided missiles work?

Current laser guided missiles work in one of two ways. The first type, a “beam rider,’ reads the laser light emitted from the launching aircraft and rides the beam toward the target. The second type uses on-board sensors to pick up laser light sent by the aircraft and reflected from the target.

How do precision guided missiles work?

Precision-guided small arms prototypes have been developed which use a laser designator to guide an electronically actuated bullet to a target. Another system in development uses a laser range finder to trigger an explosive small arms shell in proximity to a target.
