I think you will not need additional hardware. As far as I understood, you are trying to replicate my work (2x2 Beamformer), but by using two SDRs. Well, you would be extending it, as both devices could track the other.

I was able to do that with a student with access to the hardware, the challenge was to tweak the carrier synchronisation to handle the difference in the local oscillators. Honestly, we did it by trial and error. I would suggest driving each SDR with a different computer, although we did not have apparent issues when using a single PC for both SDRs, but MATLAB adds a lot of overhead and could cause frame drops.

I do not have access to her work. I'm not a professor, she was a student who landed on my repository (like you, I suppose haha). But let me know if I can help you set things up!

Of course! Let me know how do you want to show your progress (call, video...)

I can't remember the block's name, but I was plotting the Spatial Spectrum. There should be a block with a similar name.

I may have used this block. There are other blocks for the different beamformers.
