Web29 de abr. de 2010 · The signal reflects from the object, and the antenna waits for the return signal. The simplest sort of radio "imaging," then, is just radio ranging. Send out a ping, wait for the echo. Use a precise clock to time how long it takes the reflection to return to the antenna, and you know very precisely the range or distance to the target. Web3 de fev. de 2016 · When an astronomer points a radio telescope at something in space, radio waves from space hit the telescope’s surface. The surface – which may be metal with holes in it, called mesh, or solid metal, like aluminum – acts like a mirror for radio waves. WebRadio is a way of sending sounds or other information through the air. The information is carried by invisible radio waves. Radio waves are used for broadcasting, or sending out, radio and television programs.
