Primary sources
- Antenna Arraying Techniques in the Deep Space Network (NASA / JPL DESCANSO (Rogstad, Mileant, Pham)): Coherent array SNR for identical antennas scales as N. Not a DSN combiner.
- Free-space path loss (Friis / ITU-style FSPL) (ITU / standard radio engineering): L_fs = 20 log10(d_km) + 20 log10(f_MHz) + 32.44 dB form used in educational link budgets.
