At the HAARP web site for the moon bounce experiment
(http://www.haarp.alaska.edu/haarp/mbann.html), they display a graph
that shows relative power of the incident and reflected signal versus
time. They show the transmitted signal at ~ -65 dB; they show the
reflected signal at ~ -77 dB.
Are they implying that the round trip path loss to the moon and back is
only ~ 12 dB???????
It's gotta be closer to 100 dB path loss I would think. BTW, an
absolute level must be in dBm, or something similar. Plain XX dB always
refers to a comparison.
