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.
