WSTAR - The Wisconsin Small Telescope Array for Radio-waves

We propose to build three small radio telescopes, based on the designs of MIT's Haystack Observatory, in order to develop and test new techniques for interferometry. An interferometer is an array of telescopes that combines signals to generate a higher resolution image of the sky than a single, smaller antenna can create by itself.

We will build and compare an adding interferometer with a multiplying interferometer. The telescopes will also be used to investigate and map the 21-centimeter line produced by neutral hydrogen (HI) in the galaxy. We will also create a user-friendly program in which the academic community will have access to the telescopes to elicit scientific interest amongst undergraduate students.
