A Robust Capon Beamformer against Uncertainty of Nominal Steering Vector
نویسندگان
چکیده
A robust Capon beamformer (RCB) against the uncertainty of nominal array steering vector (ASV) is formulated in this paper. The RCB, which can be categorized as diagonal loading approach, is obtained by maximizing the output power of the standard Capon beamformer (SCB) subject to an uncertainty constraint on the nominal ASV. The bound of its output signal-to-interference-plusnoise ratio (SINR) is also derived. Simulation results show that the proposed RCB is robust to arbitrary ASV error within the uncertainty set.

On robust Capon beamforming and diagonal loading
The Capon beamformer has better resolution and much better interference rejection capability than the standard (data-independent) beamformer, provided that the array steering vector corresponding to the signal of interest (SOI) is accurately known. However, whenever the knowledge of the SOI steering vector is imprecise (as is often the case in practice), the performance of the Capon beamformer ...
متن کاملIterative Robust Capon Beamforming with Adaptively Updated Array Steering Vector Mismatch Levels
The performance of the conventional adaptive beamformer is sensitive to the array steering vector (ASV) mismatch. And the output signal-to interference and noise ratio (SINR) suffers deterioration, especially in the presence of large direction of arrival (DOA) error. To improve the robustness of traditional approach, we propose a new approach to iteratively search the ASV of the desired signal ...
متن کاملQuaternion-valued robust adaptive beamformer for electromagnetic vector-sensor arrays with worst-case constraint
A robust adaptive beamforming scheme based on two-component electromagnetic (EM) vector-sensor arrays is proposed by extending the well-known worst-case constraint into the quaternion domain. After defining the uncertainty set of the desired signal’s quaternionic steering vector, two quaternionvalued constrained minimization problems are derived. We then reformulate them into two real-valued co...
متن کاملRobust Widely Linear Beamforming via an IAA Method for the Augmented IPNCM Reconstruction
Based on the reconstruction of the augmented interferenceplus-noise (IPN) covariance matrix (CM) and the estimation of the desired signal’s extended steering vector (SV), we propose a novel robust widely linear (WL) beamforming algorithm. Firstly, an extension of the iterative adaptive approach (IAA) algorithm is employed to acquire the spatial spectrum. Secondly, the IAA spatial spectrum is ad...
متن کاملRobust Krylov-Subspace Methods for Passive Sonar Adaptive Beamforming
Krylov-subspace methods, such as the multistage Wiener filter and conjugate gradient method, are often used for reduced-dimension adaptive beamforming. These techniques do not, however, allow for steering vector mismatch, which is typically present in many applications of interest, including passive sonar. Here, we discuss recently proposed robust methods that do allow for steering vector misma...
