Better understanding of beamforming

Hi to all,

i am currently doing a project on ultrasound beamforming and i would like
to ask if anyone of you can recommend me some websites or books that i can
read on so as to get a better understanding of the technique itself before
starting. Thank you very much :)

I learned acoustic delay-sum beamforming from a masters thesis at my
school.  You can probably get an inter library loan.  The reference
should be in my thesis (http://signalsguru.net/projects/thesis/
thesis_page.html  -- reference 13).  I highly recommend this book as
well -- http://www.amazon.com/Statistical-Adaptive-Signal-Processing-Estimation/dp/0070400512.

The principle is trivial, just specify one or more steering
vectors and project the signal onto each one.

The problem is how to implement a working system. How large
or small arrays can you build? How do the typical sizes
compare to the wavelength of your signal? How many sensors
can you afford / find space for? Do you intend to use
narrow-band or borad-band signals? Do you look for transients
or long-term statistics? One beam only or multiple simultanous
beams? 2D or 3D?

There are no simple, generic answers. If you work on a
project, you will have a boss or supervisor who ought to
know at least the basics of your application. Ask him or her
for some basic reading material and work your way from there.
