What Are the Key Equations for a Phased Antenna Array?

[linear_shift]

What are the equations for a phased antenna array due to:

1. Individual element gain and the number of elements
2. Aperture of the array

I have been googling these for god knows how long and can't find the slightest hint, except the site Microwaves 101 (http://www.microwaves101.com/), which left out the f-ing equation I described in number one. I am building a phased array radio telescope for the UHF band (out of TV antennas) and am in dire need of these equations. Thanks, ls.

There's some math and other links at the wikipedia.org entry:

I haven't worked with arrays much, but my Antenna book by Stutzman and Thiele has a pretty good section in it. Do you have access to this book, or any other antenna books?
