direction of arrival estimation

hi all
anybody got a document explaining the direction of arrival estimation method for smart antenna as all what i got from search is too complex
i really wanna understand it , so as to start simulating it using matlab
thanks all

In classical direction finding there are two methods using fixed antennas.

One is the time of arrival differences on two different antennas. This is done with correlation methods.

The other is two antennas with orthogonal radiation patters and you use the ratio of the amplitude of the received signal (plus a correction factor).

For sinulating, this book might be a good starting point. There are MUSIC and ESPRIT algorithm reviews in this book.
