When light waves strike an object, they can interact with it in several ways: They can be reflected back like those from a mirror; they can be absorbed, which means they are captured by the object; they can be transmitted and pass through it; or they can be scattered and deflected in different directions.

Radar satellites come equipped with an antenna that sends radio waves to Earth; after hitting the planet's surface, the signal is reflected and scattered back toward a detector that generates an image without the need for visible light.
