Hello thanks for sharing your work and dataset. I have some questions about the array

What exactly is the Calibration Matrix? Is it the MIMO Spectrum for a reflector at each angle bin?
Can you share the array geometry? Do you have info on the virtual array?
How would you use an FFT or Capon Spectrum to estimate angle? (I want to compare to the Lookup Table approach)

Thanks, Isaac
