In this letter, we propose a coprime array interpolation approach to provide an off-grid
direction-of-arrival (DOA) estimation. Through array interpolation, a uniform linear array …

In this paper, we propose direction-of-arrival (DOA) estimation techniques, respectively
based on covariance matrix reconstruction and matrix completion, to achieve robust DOA …

In this paper, we propose a unified array geometry, dubbed generalized nested subarray
(GNSA), for the underdetermined direction-of-arrival estimation. The GNSA is composed of …

In this letter, a manifold reconstruction based ESPRIT algorithm is devised for direction-of-
arrival (DOA) estimation. Unlike the standard ESPRIT approach, the proposed method …

The problem addressed in this paper is focused on the direction-of-arrival (DOA) estimation
of the circular and noncircular wideband signals. The propagator scanning scheme is …

Wideband direction-of-arrival (DOA) estimation is a key part in array signal processing. The
existing algorithms for the wideband DOA estimation are often studied in the situation of …

In practical applications of array system, the incident signals may come from either circular
or noncircular sources, or both. The problem of direction-of-arrival (DOA) estimation is …

This paper proposes a novel approach to sparse recovery assisted direction-of-arrival (SR-
DOA) estimation. By exploiting the sparsity inherent in the spatial spectrum, the DOA …

In practical applications of wideband antenna‐array processing, the signals to be processed
may include either circular or non‐circular or both circular and non‐circular ones. The …

In a low-angle tracking scenario, it is difficult to get an accurate estimation of the direction-of-
arrival (DOA) due to the presence of reflection path. Direct and reflected signals are highly …
