No, I'm not confused whatsoever. You can not get the same kind of information using radar using the system you are describing. Period. You are confusing broad, beacon like radar systems (like a flashlight or a paint brush) with phased systems, which are fundamentally different.

Phased systems depend on nano-pico second scale precision in timing; you aren't accomplishing that across a distributed system. And the exact structure of the beam that is going to be formed is dependent on what the receiver has detected, whatever scan pattern is being used. They are a coupled system.
