Could you explain this again?

I understand that why are we actually applying the window. As the narrower the window is the more we can capture the area.

The FIR filter you discussed is the one that we would need for the DC removal, right? So we first have to apply the FIR filter and then the beamforming and both follows the same window based design. right?

I think i am pretty much sure of the design. I should specify it exactly first.

Thankyou dave.
