Like bats do in caves it is a signal sent out and timed so the distance can be measured from the reflected sound waves or in this case radio waves that bounce off any objects or obstacles.
they use radio waves to pick up some what satellite images or existance of things in space

A radio telescope has two basic components, a large radio antenna and a radio receiver. It is used to detect radio-frequency radiation emitted by objects in space.
To detect, track, and sometimes identify objects via the emission of radio waves. Speed radar (like those used by police) can detect nearby objects and calculate their speed. Weather radar can detect the location of clouds and rain. Air traffic radar can detect and track unidentified flying objects. With the help a monopulse secondary surveillance radar, the radar system can identify the individual planes. Higher technology radars can detect and identify distant small objects with great precision.
