Ed, what satellite was that??
Well I copied signals that were back scattered from a farm windmill in Texas on 10.368 GHz SSB. Distance was about 30-miles. I believe that the power being used was about 1-5w. I was portable on a 100-foot high hill in the Texas countryside. Direct path did not produce a strong signal.

Spots on Radars - above, infront and behind them - so yes they can cause problems to RF signals.

Trevor,
That is some pretty good stuff for higher powered xmitters...But I doubt there is any instrument sensitive enuff to measure the reflection potential from any satellite we will ever launch, and the "shadow" that it would cause on a LEO is in less than a second...HEO's may take a little longer....
This is conjecture based on my HS physics...I would appreciate comments from any of the many engineering experts we have on here...
