Re: [Discuss-gnuradio] Regarding high radar cross-section area in gr-radar simulation

[Martin Braun]

Hah yeah,

I just realized that too. However, this is what we're dealing with in
the radar world. We compensate high attenuations by high processing
gains. I'm still looking at the simulations, and will see if we can get
more realistic values in there.
