Subspace estimators of direction of arrival
Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005We consider in this paper a class of techniques for the estimation of the direction of arrival of a narrowband signal. Eigenvectors of a spectral covariance matrix corresponding to a number of the lowest eigenvalues are used to estimate the bearing. It is shown that the estimator has a non-standard asymptotic distribution.

Direction-of-arrival estimation of an amplitude-distorted wavefront
IEEE Transactions on Signal Processing, 2001In a number of array signal processing applications, such as underwater source localization, the propagation medium is not homogeneous, which causes a distortion of the wavefront received by the array. There has been some interest in the direction-of-arrival (DOA) estimation of such distorted wavefronts.

Direction of Arrival Estimation with Uniform Planar Array
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017Analog/digital/hybrid beamformer/receiver designs for mmWave communication have attracted great research attentions including directional of arrival (DOA) estimation. Traditional investigation of smart antennas for wireless communications has primarily focused on uniform linear array (ULA) antennas and there are little attention and literature on other

Decentralized Direction of Arrival Estimation
2017Richtungsschätzung (englisch: Direction-of-arrival, kurz DOA, estimation), mittels teilkalibrierter Sensorgruppen (Arrays) bestehend aus mehreren Untergruppen (Subarrays), ist ein Schätzproblem in verschiedenen praktischen Anwendungen, wie Radar, Sonar und Reflexionsseismik. Aktuelle DOA Schätzalgorithmen benötigen die Messdaten aller Sensoren an einem

Direction of Arrival (DOA) Estimation
2019The importance of DOA estimation in radar processing for automotive applications cannot be overstated. It forms the third component of the radar cube: range, velocity, and angle. In practice, DOA estimation is often complicated by the fact that there will be multiple and unknown number of source signals impinging on the receiver array at the same time,

Estimation of Direction of Arrival Algorithms
2013MUSIC and ESPRIT algorithms are two of the most widely known and used signal source estimation techniques. This study aims at the comparison of the performances of these two techniques. In this study, the signals coming toward uniform linear antenna arrays are estimated using MUSIC and ESPRIT algorithms.
