Ambiguity function

An ambiguity function is like a map that tells us how a thing called a "signal" can be seen in different ways. Think about drawing a picture on a piece of paper. When you look at the picture straight on, everything looks clear and easy to see. But if you hold the picture at an angle or move around it, the picture may look blurry or distorted.

In the same way, when we send a signal, like a sound or a radio wave, it can be viewed in different ways depending on how we look at it. The ambiguity function helps us understand how the signal might look in different situations.

The function is like a way of measuring how long it takes for the signal to travel, and how spread out it is. It's kind of like looking at a ball that someone throws. We can measure how long it takes to reach us and how far it has traveled. The ambiguity function does the same thing for signals, but it helps us measure them in different ways depending on how we are looking at them.

So, the ambiguity function is a tool that helps us understand how signals can be seen or measured in different situations. Think of it like looking at a picture from different angles or measuring a ball in different ways, but instead of a picture or a ball, we are talking about signals.
