Okay kiddo, low-probability-of-intercept radar is like a really sneaky way of sending and receiving messages without anyone else knowing. It's like a secret code that only you and your best friend know how to use.
An adult might say that low-probability-of-intercept radar is a type of radar that is hard for other radars to detect because it sends out really low power signals and changes its frequency really quickly. It's like if you and your friends were playing a game of hide and seek, but instead of hiding in the same spot every time, you kept moving around really fast so it was hard for the seeker to find you.
This type of radar is used by airplanes, ships, and even the military because they don't want anyone else to know where they are or what they're doing. It's kind of like a secret spy tool.
So, in short, low-probability-of-intercept radar is a sneaky way for planes, ships, and other things to communicate with each other without anyone else knowing. It's like a secret code that only they know how to use.
