How Do Radio Astronomers Make Images at Radio Frequencies?

-- Karen | May 1, 2025

Question:

How do radio-astronomers get visual images from radio frequencies or waves?

-- Karen

Answer:

I believe that this question has been answered before in two posts which addressed questions about single radio telescopes (How Does a Single Dish Telescope Make Images?) and collections of radio telescopes which work together to make an astronomical image (How Does a Radio Interferometer Work?).
