Lal Chand Godara (editor), CRC Press
...also, to this classical books:
Introduction to Adaptive Arrays
R.Monzingo and T.Miller Wiley
Array Signal Processing: Concepts and Techniques
Jhonson and Dudgeon. Prentice-Hall
...also, take a look for papers in the IEEE, for example:
"Adaptive array antenna beamforming architectures as viewed by a microwave circuit designer"
