- Direction-of-arrival (DOA) estimation is a fundamental area of research in the field of array processing, as it applies in a variety of areas, including: sound field analysis, spatial sound reproduction and spatial filtering. There exists a plethora of DOA estimating algorithms, which all vary in terms of accuracy and computational complexity. Among the most popular approaches for DOA estimation are the steered-response power, time-delay based, active intensity based and subspace based methods. In this work, DOA estimation in spatially constrained areas is explored. A spatially constrained version of the active intensity vector is first formulated, which is then utilized for the DOA estimation. This work elaborates on this concept and demonstrates its advantages when compared to conventional approaches
