Two decades of statistical array processing
Mats Viberg, Hamid Krim · 2002
Array signal processing is the common name for a large number of signal processing techniques involving parameter estimation from multichannel data. The prototype problem is to find the directions of incoming wavefronts using an antenna array. The applications are numerous, including unexpected problems not involving spatially distributed sensors. A vast number of estimation methods have been proposed and extensively analyzed over the last 2-3 decades. The paper provides an introduction to the various algorithms.
