Dear Andrew,
Hm, this is all getting confusing; an uncommented screenshot doesn't
help. Why would you want to pull the doppler shifted signal from a plot
(which is a reduced representation of your signal), if you have access
to the original signal?
Also, you're still very much only describing in,
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
Ok like the primary radar I have spent 7 years working on
How do I pull out doppler shifted signal from a waterfall spectrum
The doppler shift is slow though
Not a chirp but a slow 5 minute chirp

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 -

Perhaps you can use this to analy
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
Sorry you misunderstood my question
I want the doppler shift of the satellites to be very distinct from the station
with no doppler shift
Much like doppler shift radar perhaps
But the change in frequency can be minutes long for the satellite pass

Sorry this is new to me
I have just worked out I can see satellites in a waterfall display due to their
doppler shift
I think that lends itself to meteor shower
Can gnu radio be used to assist pulling out the doppler signals from the non
doppler ones ?
I guess this would require some sort of
