Hi all!
I'm Wonjineom.
I want to use mmWave Radar for our machine vision system and I have a question.
I know that the FMCW signal can penetrate all materials except metal, then how can the sensor recognize some material?
I guess that some of the wave is reflected and other penetrate the material. Is it right?
I already saw the post below

But I can not be sure about this issue.
Thank you.
