I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.
Radio telescope, usually a microwave dish with a movable parabolic reflector.
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.
All Radio Telescopes form images of astronomical objects using a frequency of the electromagnetic spectrum (radio waves) that human eyes can not detect. This tells us things about these regions of space that we cannot learn in other ways.
