in TI's mmWave device overview_AWR1x.pdf, I found clustering module in the signal processing flow ,
1DFFT->2DFFT-> detection-> 3DFFT(DOA) -> Clustering-> Tracking-> Object Classification
Q1: What's purpose of part of Clustering? and how to implement it?
Q2: What does Object Classificaton based on? based on target's width and height? I think we can only get simple classification,e.g., large car, medium car and small car. Is it possible to distinguish human from car based on current TI technology?
