If you want to use a radio telescope to bounce radar signals off of a planetary body, what do you need to attach to the telescope that wouldn't normally be there?


AA receiver that can detect the bounced signals when they come back to Earth
BA mechanical mounting system to enable the dish antenna to track the sky as the Earth rotates
CA transmitter that will create a powerful signal to be beamed outward

Verified Answer :

Final answer:

To use a radio telescope for bouncing radar signals off a planetary body, you need to attach a transmitter to create a powerful signal. The telescope's primary purpose is to receive those reflected signals from the planetary body. This combination allows scientists to gather data about celestial objects effectively.


Explanation:

Using a Radio Telescope for Radar Signals

If you want to use a radio telescope to bounce radar signals off of a planetary body, you need to attach a transmitter that will create a powerful signal to be beamed outward. Normally, radio telescopes are designed to receive signals from space, such as radio waves emitted by astronomical objects, but in this case, you require additional equipment to send out radar signals.

The process works as follows:

  1. The transmitter sends out a strong radar signal towards the target planetary body.
  2. The planetary body reflects the radar signals back toward Earth.
  3. The radio telescope functions as a receiver, detecting the signals when they return.

This method has been used in past missions, such as when NASA's Goldstone Observatory tracked planets by sending radar signals and analyzing the returning echoes to gather data about their surface and atmosphere.
