WOW, this appears to be geometrically distorted. I am assuming this swirling effect is due to the Bi-Static relationship of the antennae. Also I assume that this geometry distortion or swirling effect around a central hub will be different with different Transmitters. When are we going to see a display with two different transmitters? Good luck to you Juha.
Amazing work! I have been looking at some basic doppler shifted backscatter signals from aircraft and satellites with my funcubedongglepro and RTL SDR's at 64Mhz and 182Mhz (we still have some high powered analogue tv transmitters here until the end of the year). would love for someone to produce something like this for Windows based PC's. Great work!
Was just wondering whether it may be possible to use a local narrowband digital trunking control channel to provide the necessary timing signal. With a nice narrow digital signal, containing regular timed pulses, it may be possible to utilize such a signal to produce more accurate result?? Albeit at reduced range obviously.
I haven't worked on this for about 10 years. This turned out to be just a fun demonstration. I think the concept is viable, but I just don't have interest in tracking aircraft. I am more interested in meteors, ionospheric plasma, and planetary targets. These are more approachable with controlled radar experiments with dedicated radar systems.
Updated my code. Now I'm using inverse filter self-noise/ground clutter removal, and I also got this thing to run in real time.

Hello @juuuuuusto, your work is really amazing, can you please share the source code/Raspberry Pi image?

Hello, how is the project going 10 years after the video was published?

@@juhavierinen very good!
