Currently, I already have an FMCW data matrix which was acquired by the SISO radar. Based on this data matrix, I want to estimate number of targets in it. And then I can apply some blind source separation algorithms.

Blind source separation problem always knows the number of sources as prior knowledge. But now I need to estimate it.

I tried AIC and MDL methods, but they also failed. I am not sure if it is because of the SISO radar structure. Shall I recollect the data by using the MIMO radar?

  • $\begingroup$ "FMCW data matrix": you'll need to define what that matrix contains. It's not a fixed term, but depends on your modelling. $\endgroup$ – Marcus Müller Feb 13 at 14:53
