The COSETI Observatory

  • Comparisons of Interstellar Link Performance for the following Electromagnetic SETI systems:

    • Microwave SETI
    • Infrared SETI
    • Visible SETI
      • All transmitters normalized to a
        1 kW reference power for comparison purposes only.
      • Performance compared on a spectral density and SNR basis.
      • At 10 light years range, a 1 GW visible laser transmitter could result in a 94 dB SNR referred to a 1 Hz bandwidth.
