The set-up that I think I did a pretty bad job describing earlier goes
USRP ---> tx antenna ~~~~~~ AIR GAP ~~~~~~~ RX antenna ----> some
components from an old microphone -----> PC sound card. I believe your
theory about non-linearities creating a sort of envelope detection is
accurate, but I think it might be the non-linearities of the
microphone's amplifier that are the component that are doing the
envelope detection. I've begun reading more about Nyquist rates.
Thanks for all your responses, they've been very educational.
