DOA Estimation

Hi all,
   I am working in Array Signal Processing. In that i need DOA
estimation. So if any one had Matlab code for DOA Estimation or any
one can tell how to fine DOA, it would be great help
So please help me

Thanks in advance

Check out 

van Trees: Detection, Estimation and Modulation Theory, vol IV:
    Optimum Array Processing.

No matlab code, but an OK place to start.

The matlab code for Stoica's book on spectral estimation (including
DOA) can be found at

I just finished a course on Array Signal Processing, and we used
the book from Van Trees, "Optimum Array Processing".  They do have
Matlab code and examples -- I'm pretty sure they have samples for
DOA, both for single source and for multiple source planewaves.

Not sure if they have parts of that code freely available online,
but you might want to try.  I can't find the book right now, but
do a search (check Amazon, for instance) to find out the editor's
website and check there to see if you find the samples.


HTH,

Go go Yahoo, and search for MUSIC algorithm, and you will find
something about DOA estimation. Actually, MUSIC is one of DOA
algorithms, and many other DOA algorithms are derived from it. I think
it is a good start to learn MUSIC algorithm for DOA.

Just search for Angle Superresolution algorithms.  There's quite a number of
them including:
MUSIC (and its many variants, including Root-MUSIC, Reduced MUSIC), Capon,
Maximum Entropy Method, Kumaresan & Tuft, Pisarenko, Recursive Suppression,
Parametric Fitting etc. etc.  I have some basic Matlab code to do some of
these if you're desperate, but it might be more constructive for you to have
a go yourself :-)

Ta,
Carlos

Chowdry, 

The following is paper on adaptive array processing using
detection-guided NLMS algorithm.

http://eprint.uq.edu.au/view/person/Selvaraju,_Vigneswaran.html

Hope the paper is useful. If you can explain a bit more on what
exactly you are trying to do, I might be able to point you in the
right direction.

Damn fine paper, Vic!

Hi Carlos,

  I am working on DOA Estimation using High Resolution Spectral
Analysis. I already written some matlab code but it is not working
fine. So if you don't mind can you send your code so that it will help
me where i am going wrong.

ok
Thanks
Bye

Hi all,
 
    Can any give me Generalized formula for Power Spectrum in Maximum
Entropy Method in DOA Estimation

Thanks in Advance

bye
chowdary.
