The Allen Telescope Array (ATA) was developed by the SETI Institute and the Radio Astronomy Laboratory (RAL) at the University of California, Berkeley to construct a radio interferometer that is dedicated to radio astronomy observations. At the same time, it is also used for the search for extraterrestrial intelligence.[1][2]

The ATA is at the Hat Creek Radio Observatory, 290 miles (470 km) northeast of San Francisco, California. The goal is to have 350 antennas.[3] To start, 42 antennas (ATA-42) were put to work on 11 October 2007.[4][5] However, a lack of money stopped operations in April 2011.[6][7] In August 2011, ATA got short-term funding.[8] In 2012 UC Berkeley quit the project.

It is named after Paul Allen, the co-founder of Microsoft. Its old name was the One Hectare Telescope (1hT).
