I really like the book Adaptive Array Processing by Allen and Ghavami. It
makes clear distinction between wideband and narrowband arrays. It treats
both problems clearly in the time domain and the "array pattern" or
transform domain. It has a download site
ftp://ftp.wiley.co.uk/pub/books/allen
with all of the book figures, some matlab files, chapter 4 as a teaser and
the soluitions manual to the problem set.
ALL of the automated adaptation algorithms of interest to us, FM, Capon,
Espirit, ML, etc. are discussed in more than sufficient detail to actually
program them. One is taught the difference in Wiener, LMS, and RLS and
maximum likelihood (ML) approaches to arrays. The book is short and sweet
at 250 pages and is available used on Amazon used for just over $50.

Subject: [Mep-dev] Antenna Meeting, Discovery Document, and SBMS meeting
Greetings to the list!
I have some progress to report on discovery and antennas. First, the antenna
update.
I had a meeting last week with an engineer at a local wireless company that
is interested in helping with the groundsat (repeater) antenna. His name is
Ernie Ozaki, and he's worked on radar, cellular, and other systems. He
recommended a book called Introduction to Adaptive Arrays by Robert A.
Monzingo and Thomas W. Miller (to keep me off the streets and out of
trouble), and is very interested in seeing what we come up with for antenna
requirements. This brings the antenna crew up to just shy of a half dozen.
In order to draft the antenna requirements, we need to settle some of the
open issues about the link budget. I'd like to walk through what we know and
don't know next week, and then take a stab at doing a terrestrial link
analysis. Back of envelope so far indicates that 10W is total overkill for
10MHz bandwidth, which is great news. I'd like to work up a document that
clearly states just how fast and far we can expect to go.
More soon!
