Video script & Narration

Hello, class. Welcome to my video. Here I'm going to be giving a brief explanation of how radars work and then a picture of actually, when the radar comes back, the signal comes back, what happens and what you can see. So first here you'll see here starts with this transmitter. The transmitter puts a signal into the duplexer. The duplexer both receive signals and puts out signals. As you can see right here, the duplexer sends the signal out to the antenna, which shoots. This will be this line right here. It shoots that signal out towards an object. Once the signal hits the object, you'll see right here, it comes back to the antenna. And this is where, really, the only time the signal is outside of the system is when it's either getting shot at the target or getting shot back towards the target. After this, the radio wave comes back into the antenna. It's inputted back into the duplexer. But instead of going to the transmitter this time, it comes down and goes into the receiver. The receiver processes the information and puts it out to the display. The display is normally a computer, and with different systems come different displays. This picture here that I'm going to show you is a picture of a Navy radar. This would be a 360 degree radar that the Navy has taken and can see in 360 degrees and can see down to a 10th of a mile, of a position, of a ship out on the water, of an aircraft, or even of a submarine in sub radars. This is a very cool use of technology, and it's used all the time in our world, whether it's weather, naval systems or multiple other resources.
