👉 A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of sent radio waves (usually microwaves) reflected from their surfaces
Alright class, settle down now, let’s dive into this today! We have a tricky word here - “radar.” It sounds like something out of a sci-fi movie, doesn’t it? Let’s break it down nice and slow. The dictionary gives us a pretty good explanation, but let's make it easier to understand with a little rhyme: “Radar” stands for R adio D etection and R anging – that’s the key! It’s all about detecting things far away. Think of it like this: We send out radio waves, like little signals in the air - microwaves are a type we use with care! These waves bounce back when they hit something – a ship, an airplane, or even clouds so high! The radar then analyzes how those waves return, to figure out where and how fast things fly. It’s not just about finding what is there, but also how far away it is, and moving with a speedy pace! It tells us position, velocity - that's its special grace. Does that make sense? Any questions before we move on to the next topic? Don't be shy – ask if you’re feeling unsure!
