Okay kiddo, so you know how when you play hide-and-seek, you try to sneak past your friends without them noticing you? Well, radar jamming is kind of like that, but instead of friends looking for you, it's machines called radar.
Radar is a way for people to see things that are far away, like airplanes or ships. It works by sending out a signal that bounces off of things and comes back to the radar machine. Then, the machine can tell where the object is and how far away it is.
Now, let's say an airplane doesn't want to be seen by the radar. It might try to jam the radar signal by sending out a lot of noise or interference. This makes it hard for the radar machine to pick up the airplane's signal, so the radar operator won't know where the airplane is.
Deception is kind of like jamming, but instead of sending out a lot of noise, the airplane will try to make the radar signal think it's something else. For example, if the radar is looking for airplanes, the airplane might make itself look like a bird or some other kind of flying thing. This confuses the radar machine, and it might not even pick up the airplane's signal at all.
So, radar jamming and deception are ways for airplanes to stay hidden and not be detected by radar. It's kind of like playing hide-and-seek with a machine, and the airplane is trying to sneak past without being seen.
