Thank you Marcus and the others for your inputs,

I created the flow almost from scratch taking into consideration your  
words  
and I came up to this aspect.

Here they are:

I added delays to simulate targets. I didn’t manage to see any Doppler

What am I doing wrong?

Thank you for your time.

Dimitris.
