Hello, i heard that the general collage formula is just an aprroximation for N>>1 as shown bellow.
Does anybody know how we develop this "non approximated formula from the basic Grating Lobe theory?
Thanks.

Those look like excerpts from Balanis' text; I think he walks through the derivation. You just have to re-perform it without making the approximations he does, I think in the earlier equations.
