I am also unable to understand what you aim (or problem) is but if it can be of any use to you, a small movie of 24 hour of GRAVES radar recording is available at http://jmfriedt.free.fr/1707_graves_36h.ogg Horizontal axis is Doppler shift in Hz (df=2*v/c*143.05 MHz, or a velocity of 750 km/h for

Hi Marcus, Concerning DRM here in Brazil, there is not much activity because of the immense delay from the government to adopt any standard. Me and a bunch of hams are carrying some trials with DRM in HF, but just this (from Parque do Rodeador, an EBC facility). But DRM signals are always on... in

That's why I said "inspirational". Being familiar with what others have done with regard to doppler estimation and correction might help you reuse some parts of their work. Another module that might help is gr-inspector - https://github.com/gnuradio/gr-inspector. Perhaps you can use this to analy

Dear Mehtap, Both the blks2 TCP source as well as the Blks2 Packet encoder are deprecated. I doubt we'll be able to fix it. So, I'd recommend switching to the more flexible packetizer architecture you'll find in the /usr/share/gnuradio/examples/digital/packet/ ; look at packet_loopback_hier

So, adapt the scale with which you look at things. I think your question could actually use a lot of "describe the problem that you're actually having". The point is that you don't really seem to understand how you'd "pull the doppler signals" out of a combination of signals. Now, we all love
