An architecture for DOA estimation for broad-band sources
R. Tabar, Mohsin M. Jamali, Subhash C. Kwatra · 1993
High-resolution direction-of-arrival (DOA) estimation is important in many sensory systems like radars, sonars and seismic exploration. With the advances in the area of VLSI it is now possible to design a special purpose hardware for DOA estimation which will be suitable for real-time sonar applications. One of the methods for DOA estimation for broad-band sources proposed by Buckley and Griffiths [1988] has been selected for hardware implementation. This BASS-ALE algorithm has been simplified, parallelized and is mapped on an architecture suitable for real time processing.>
