matrix P (23). From (24a) it is clear that the maximum number of sources that a ULA can resolve is M-1 the number of sensors in the array. This occurs when the sources are fully incoherent with ρ^ₛ = M-1. What the authors’ interestingly point out is that theoretical upper-bound in (24) reaches this
