Steering Vector and Signal Estimation for Uncalibrated Polarization Sensitive Arrays

Digital Signal Processing, 1996
Abstract Weiss, A. J., and Friedlander, B., Steering Vector and Signal Estimation for Uncalibrated Polarization Sensitive Arrays,Digital Signal Processing6(1996), 37–50. We consider the problem of estimating the steering vectors of an uncalibrated diversely polarized array. The array elements are assumed to consist of several groups.

Multidimensional Parameters Estimation of Array Signal Based on Steering Vector

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
This paper exploits rotation invariance of matrix pencil based on two parallel uniform linear polarization sensitive arrays, and eigenvalues and the corresponding eigenvectors of the matrix pencil are the rotation matrix and time-space-polarization steering vector of the subarray, respectively.

Which cumulants should be selected for steering vector estimation?

Proceedings of the IEEE Signal Processing Workshop on Higher-Order Statistics, 2002
Cumulants have been successfully applied in the area of narrowband array signal processing. This motivates a performance analysis to find out the strengths and the weaknesses of each new algorithm. Hitherto, most of the known performance analyses are based on the asymptotic covariance of sample cumulants and are therefore called asymptotic performance ...

Effect of Steering Vector Estimation on MVDR Beamformer for Noisy Speech Recognition

2018 IEEE 23rd International Conference on Digital Signal Processing (DSP), 2018
The minimum variance distortionless response (MV-DR) beamformer is a widely used beamforming technique that extracts sound components coming from a direction specified by a steering vector. In this paper, we present four different steering vector estimation methods and analyze their influence on the MVDR beamformer in speech recognition.

"Almost blind" steering vector estimation using second-order moments

IEEE Transactions on Signal Processing, 1996
The problem of separation and reconstruction of superimposed signals using an array of sensors attracted considerable interest. The estimation of the steering vectors of an uncalibrated array is considered. We identify a cost function whose minimizer is a statistically consistent estimate of the unknown parameters.

Off-Grid Direction-of-Arrival Estimation Based on Steering Vector Approximation

Circuits, Systems, and Signal Processing, 2018
In this paper, a novel off-grid direction-of-arrival (DOA) estimation algorithm is proposed based on steering vector approximation. The conventional multiple signal classification (MUSIC) technique estimates the DOA with a uniformly discretized grid by assuming that the true DOAs lie on the grids. In practice, this assumption is rarely satisfied.

Experimental Study on MUSIC-Based DOA Estimation by Using Universal Steering Vector

IEICE Transactions on Communications, 2008
MUSIC-based estimation of direction of arrival (DOA) using universal steering vector (USV) is experimentally studied. A four-element array antenna and a four-channel receiver are employed for the experiment. In order to improve the accuracy of DOA estimation, USV which has already included the effect of mutual coupling between array elements and effect

A Robust Adaptive Beamforming with Diagonal Loading and Steering Vector Estimation

2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT), 2019
A number of robust adaptive beamforming methods have been developed in recent years. These methods suffer from performance problems, some in low SNRs and others in high SNR especially when the desired signal is present in the sample training data. Among these approaches, the diagonal loading have proved the robustness in low SNR even for small size ...

Algorithm for steering vector estimation using second order moments

Conference Record of The Twenty-Ninth Asilomar Conference on Signals, Systems and Computers, 2002
The increasing use of the electromagnetic spectrum is expected to present a higher demand for effective methods for interference canceling and signal separation. The goals of signal separation/reconstruction and interference canceling can be achieved by estimating the steering vectors of the array and then exploiting this information.

DOA and steering vector estimation using a partially calibrated array

IEEE Transactions on Aerospace and Electronic Systems, 1996
We consider the problem of estimating directions of arrival (DOAs) using an array of sensors, where some of the sensors are perfectly calibrated, while others are uncalibrated. We identify a cost function whose minimizer is a statistically consistent and efficient estimator of the unknown parameters-the DOAs and the gains and phases of the uncalibrated
