A Robust Direction-of-Arrival (DOA) Estimator for Weak Targets Based on a Dimension-Reduced Matrix Filter with Deep Nulling and Multiple-Measurement-Vector Orthogonal Matching Pursuit

A Robust Direction-of-Arrival (DOA) Estimator for Weak Targets Based on a Dimension-Reduced Matrix Filter with Deep Nulling and Multiple-Measurement-Vector Orthogonal Matching Pursuit

In the field of target localization, improving direction-of-arrival (DOA) estimation methods for weak targets in the context of strong interference remains a significant challenge. This paper presents a robust DOA estimator for localizing weak signals of interest in an environment with strong interf...
