To overcome this difficulty, radio astronomers use multiple radio telescopes at the same time, a technique called interferometry. This gives angular resolutions of 0.001" or better by effectively creating a single telescope as large as the distance between the two farthest telescopes.
Do radio telescopes use interferometry?
This is how the VLA works, by using a technique called interferometry. Since a radio telescope interferometer can combine measurements from each of the pairs of antennas in an array simultaneously, it can make a very high resolution measurement of a specific point in the focal plane of the radio telescope.
