Abstract: Abstract This paper proposes a novel algorithm for Two-Dimensional (2D) central Direction-of-Arrival (DOA) estimation of incoherently distributed sources. In particular, an orthogonal array structure consisting of two Non-uniform Linear Arrays (NLAs) is considered. Based on… read more here.

DOI: 10.1109/lsp.2025.3569465
Abstract: Coherently distributed (CD) sources are typically characterized by their direction of arrival (DOA) and angular spread. Traditional distributed signal parameter estimation (DSPE) methods for CD sources rely on a computationally intensive two-dimensional spectral search, which… read more here.

Abstract: This correspondence proposes two direct position determination (DPD) algorithms for incoherently distributed sources based on covariance matching estimation technique (COMET). First, a low-complexity estimator DPD-COMET is obtained via least squares fitting between the sample covariance… read more here.
