Spatial sampling frequency equation
The spatial sampling frequency of a linear array with equidistant sensor (antenna) spacing on the $x$-axis is simply given by
$$f_x=\frac{1}{d}\tag{1}$$
where $d$ is the distance between the sensors …

How to derive the "well-known" solution to Unconstrained Array Gain?
You can solve such a problem using the method of Lagrange multipliers. First note that maximizing the expression in your question is equivalent to minimizing the inverse function:
$$\min_{\mathbf{w}}\ …
