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 Andrew > On 23 Aug 2017, at 3:26 pm, Chr

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

Dear Mohammad, Basically, what you want to do has been a bit "hyped" under the term of "full duplex" in the last years. Essentially, all you need to do to still be able to receive while you transmit is cancelling out the effects of your known transmission on your reception. For systems with large
