How did Project Phoenix search for extraterrestrial intelligence?
Project Phoenix used the world’s largest telescopes (40 to 300 meters in diameter) to scrutinize the vicinities of nearby, sun-like stars. Stars are examined one by one over a portion of the microwave region of the electromagnetic spectrum for artificially produced signals. The Targeted Search System looks for signals in the range 1,000 MHz to 3,000 MHz, with a frequency resolution of 1 Hz. The ability to detect slowly-drifting signals and the application of near real-time data processing made Project Phoenix the most comprehensive and sensitive SETI search in the world.
