Research on 2-D Direction of Arrival (DOA) Estimation for an L-Shaped Array
Remote SensingLately, there has been a significant increase in interest in coprime array configurations, as they offer the advantage of generating more extensive array apertures and enhanced degrees of freedom when contrasted with standard linear arrays. This document introduces an innovative two-dimensional direction-of-arrival (2-D DOA) estimation technique ...

Direction of arrival estimation algorithm: Direction lock loop [PDF]
, 2002 - In this paper, a new direction of arrival (DOA) estimation algorithm, direction lock loop (DiLL), is proposed. It has a similar concept to the delay lock loop (DLL) that is used for synchronization.

Effects of reference sound speed on underwater acoustic direction-of-arrival estimation with horizontal plane array [PDF]
JASA Express LettersDirection-of-arrival (DOA) estimation of an underwater acoustic target is usually dependent on the selection of reference sound speed. For a horizontal line array, severe error of DOA estimation is induced when reference sound speed diverges from phase ...
