Sugar Grove Station was an outpost designed to listen in on Soviet radio signals reflected off the moon. How would this work? Wouldn't the radio signals be distorted by the imperfect surface of the moon? And wouldn't they also be extremely weak since they wouldn't be beamed directly at the moon?
I can't comment in detail but Earth-Moon-Earth communication at radio wavelengths is well established.
At wavelengths longer than a few cm (frequencies below 10 GHz), the Moon appears smooth and acts like a reflective sphere as far as radio waves are concerned.
