Okay, so let's imagine you're playing hide-and-seek with your friends. You're the seeker and you have to find your friends who are hiding in the park. But there's a problem, you can't see them because they're hiding behind trees and bushes.
But wait, what if you had a magic tool that could help you find them? This is kind of what active radar homing does. It's a tool that helps airplanes and missiles find targets that are hiding from them.
So how does it work? Just like you calling out "Marco" in the game, the active radar sends out a signal that bounces off of an object and comes back to the radar. The radar then uses this signal to figure out where the object is hiding.
The radar can also tell if the object is moving or not, which is important for things like missiles. If a missile is flying towards a target and the target starts moving, the radar can detect that and tell the missile to change course and follow the moving target.
So when you're playing hide-and-seek, think of active radar homing as your magical tool that helps you find your friends, even if they're hiding behind trees and bushes.
