Inverse synthetic-aperture radar
Inverse Synthetic-Aperture Radar is a technique used to create high-resolution images of objects on the ground or any other target from a far distance.
Okay, let's imagine you have a toy car, and you want to take a photo of it using your camera. If you place the car right in front of your camera, you'll get a clear image of it. But what if you want to take a photo of the car from a hundred feet away? It would be too small to see, right?
Now, suppose you have a special camera that takes multiple pictures of the car from different angles while moving around it in a circle. These pictures are all taken from different positions but of the same object. To create a clear and detailed image of the car, you can combine all these pictures taken at different angles, and the result is a high-resolution image of the car.
And that's what Inverse Synthetic-Aperture Radar does too. Instead of a camera, it uses radar waves to take multiple pictures of the target from different angles from a far distance. It sends out electromagnetic waves towards the target and receives the waves that bounce back. The waves captured by the radar are then combined using complex mathematical algorithms, to create a 2D or 3D image of the target.
In simple words, Inverse Synthetic-Aperture Radar creates a clear image of targets that are not easily visible from the ground by combining several radar images at different angles.
