Underdetermined Wideband DOA Estimation for Off-Grid Sources with Coprime Array Using Sparse Bayesian Learning
Sparse Bayesian learning (SBL) is applied to the coprime array for underdetermined wideband direction of arrival (DOA) estimation. Using the augmented covariance matrix, the coprime array can achieve a higher number of degrees of freedom (DOFs) to resolve more sources than the number of physical sensors. The sparse-based DOA estimation can deteriorate the detection and estimation performance be...
متن کاملOptimal Array Geometries for Wideband DOA Estimation
We consider the role of array geometry on the Direction of Arrival (DOA) estimating performance of the array where the impinging signal is wideband. We concentrate on arrays that have isotropic performance. An isotropic array is one whose Cramér Rao bound (CRB) on the DOA of a single source is uniform for all angles. We derive the necessary and sufficient conditions on the location of array ele...
متن کاملDifferent Wideband Direction of Arrival(DOA) Estimation methods: An Overview
This paper presents an overview of different types of wideband direction of Arrival (DOA) estimation methods. Direction-finding algorithms have straight forward applications in Sonar and Radar, and are also useful in advanced satellite and cellular communication systems for adaptive beamforming of smart antennas. Coherent Signal Subspace Processing (CSSM), one of the earliest wideband DOA estim...
متن کاملFractional difference co-array perspective for wideband signal DOA estimation
In recent years, much attention has been focused on difference co-array perspective in DOA estimation field due to its ability to increase the degrees of freedom and to detect more sources than sensors. In this article, a fractional difference co-array perspective (FrDCA) is proposed by vectorizing structured second-order statistics matrices instead of conventional zero-lag covariance matrix. A...
متن کاملDOA Estimation Exploiting Coprime Frequencies
Coprime array, which utilizes a coprime pair of uniform linear subarrays, is an attractive structure to achieve sparse array configurations. Alternatively, effective coprime array configurations can be implemented using a uniform linear array with two coprime sensing frequencies. This enables the integration of the coprime array and filter concepts to achieve high capabilities in meeting system...
