Direction of arrival (DOA) estimation from the perspective of sparse signal representation
has attracted tremendous attention in past years, where the underlying spatial sparsity …

In this article, a general introduction to the area of sensor array and multichannel signal
processing is provided, including associated activities of the IEEE Signal Processing Society …

Recently, nonuniform linear arrays (eg, coprime/nested array) have attracted great attention
of researchers in array signal processing field due to its ability to generate virtual difference …

Direction-of-arrival (DOA), power, and achievable degrees-of-freedom (DOFs) are
fundamental parameters for source estimation. In this paper, we propose a novel sparse …

In this work, we present a new coprime array structure termed thinned coprime array (TCA),
which exploits the redundancy in the structure of existing coprime array and achieves the …

In this letter, we devise an efficient approach for estimating the directions-of-arrival (DOAs) of
coherent signals using coprime arrays. Specifically, we firstly derive an augmented uniform …

Different from conventional phased-array radars, the frequency diverse array (FDA) radar
offers a range-dependent beampattern capability that is attractive in various applications …

In this paper, we develop a general framework of multi-frequency sparse array to estimate
the direction-of-arrival (DOA) of a significantly higher number of targets than the number of …

In this letter, we develop an effective algorithm for direction-of-arrival (DOA) estimation of
coherent sources with coprime arrays. Firstly, we generate a virtual uniform linear array …

In this paper, we propose a generalized co-prime multiple-input multiple-output (MIMO)
configuration for direction of arrival estimation. Compared with the conventional coprime …
