  • SETI and Signal Leakage: Where Do Our Transmissions Go?

    The paper provides a table showing stars encountered by transmissions to the spacecraft sorted by the year we could expect a return transmission if a civilization noted them, along with data on the time spent by the star within the transmission beam. DSN transmissions are several orders of magnitude smaller in EIRP than the Arecibo planetary radar (1012 W), but it’s also true that the positions of the spacecraft, and hence background stars during transmissions, are better documented than background stars that would have encountered the Arecibo signals.

    • Still ignores the calculation for recieved signal strength at target and the question: "could we identify that signal if we were there to catch it?"
