A Geographically-spaced Synchronized Signal Detection System (April 4, 2018)

A system has been designed and implemented that makes simultaneous geographically spaced time-and-frequency-synchronized measurements of hypothetical extraterrestrial narrowband signals in the 1405-1448 MHz band. One radio telescope is the Sixty Foot Deep Space Exploration Society Plishner Telescope in Haswell, Colorado, and the second radio telescope is the Forty Foot Telescope in Green Bank, West Virginia. A GPS-signallocked reference oscillator and a digital back-end is used at each site to permit differential Doppler measurements to a precision of +-1.8 Hz. This presentation will describe the system, observations of simultaneous close-frequency pulses, and future plans to enhance capabilities of the system.
