When you search your lost keys with a flash lamp, when bats detect obstacles during their night flight, or when car radars locate other cars on the road, the very same physical principle works. Be it light, sound, or an electromagnetic wave in general, a probe beam is sent ahead, and a reflected wave of the same kind carries the relevant information back to the detector.
