How Missile Guidance System Work?

Summary

This video explains the workings of guided missiles, highlighting their intelligence and accuracy in hitting targets over 6,000 km away. It covers the missile's two main phases: the mid-course, where an inertial navigation system controls its path using gyroscopes and accelerometers, and the terminal phase, where an active radar homing system locks onto the target. The guidance system analyzes the time of reflected radar signals to determine the target's position, speed, and direction. The missile then uses a terminal guidance system to accurately strike and explode upon impact. Advances in technology have led to even more sophisticated weaponry, including robot and satellite-controlled systems.

Takeaways

• 🎯 Guided missiles are highly intelligent and can adjust their path to hit distant targets.
• 📡 These missiles can accurately strike targets over 6000 km away.
• 🚀 A missile's flight path is divided into two phases: Mid-Course and Terminal Phase.
• 🧭 In the Mid-Course phase, the missile relies on an inertial navigation system using sensors like gyroscopes and accelerometers.
• 📟 The inertial navigation system controls the missile's orientation and velocity during its flight.
• 🔍 In the Terminal Phase, the missile uses an active radar homing system for precise targeting.
• 📡 The active radar system transmits electromagnetic waves, which bounce back from the target to provide positional data.
• 💻 The received information is sent to the autopilot computer to keep the missile stable and on course.
• 🎯 A terminal guidance system, often with pre-programming or a digital scene matching area correlator system, helps the missile find and hit the target.
• 🤖 Advanced weapons are being developed, controlled by robots, drones, or satellites, enabling rapid enemy elimination.

Q & A

What is a guided missile?

A guided missile is an intelligent weapon capable of changing its course to accurately hit a target, even from a distance of more than 6000 km.

How does the missile navigate during its mid-course phase?

During the mid-course phase, the missile uses an inertial navigation system that relies on motion and rotation sensors, such as gyroscopes and accelerometers, to control its orientation and velocity.

What is the role of the active radar homing system in missile guidance?

The active radar homing system is installed in the missile and sends out electromagnetic radiation toward the target. The radiation bounces back, and the missile's receiver collects this data to determine the target's position, direction, and speed.

What are the two main phases of a missile's flight path?

The two main phases of a missile's flight path are the mid-course phase, where it uses an inertial navigation system, and the terminal phase, where it employs active radar homing for precise targeting.

How does the missile use the information gathered from the radar system?

The missile’s guidance system uses the time it takes for the electromagnetic radiation to return, calculating the target’s position, direction, and speed. This information is sent to the autopilot computer to adjust the missile’s flight path.

What is the function of the autopilot computer in the missile system?

The autopilot computer uses the information from the radar system to maintain the missile at its aerodynamic level and ensure it stays on course toward the target.

What happens during the terminal phase of the missile's flight?

In the terminal phase, the missile uses its active radar homing system to track the target precisely, and it employs terminal guidance to adjust its path for an accurate hit.

What is a digital scene matching area correlator system in missile guidance?

A digital scene matching area correlator system is a technology used by missiles to match the visual or radar scene of a target with pre-programmed data to accurately locate and strike the target.

How does the missile explode upon hitting the target?

The front part of the missile is designed to detonate on impact, causing an explosion when it hits the target.

How are modern weapons, such as missiles, controlled and operated?

Some modern weapons are controlled by robots or drones, while others are guided and controlled by satellite systems from space.
