2D DOA estimation based on matrix method and joint diagonalization technique

open access: yesTongxin xuebao, 2013
When space phase factors are the same in one direction or two orthogonal directions,the convensional direction-of-arrival methods cannot estimate DOA effectly,resulting in performance degradation.Therefore,joint diagonalization technique was utilized to ...

Development of Monitoring Methods for a GPS based Smart Antenna System

open access: yesACI Avances en Ciencias e Ingenierías, 2013
One of the key parameters in the processing system of a smart antenna system is the direction of arrival of the signal of interest (DOA). DOA’s estimation traditionally performed spectral analysis on the signal received by the antenna array ...

Comparison of Direction of Arrival (DOA) Estimation Techniques for Closely Spaced Targets [PDF]

open access: yesInternational Journal of Future Computer and Communication, 2013
This paper deals with different beamforming techniques for DOA estimation. High resolution techniques such as Multiple Signal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) which are subspace based techniques are also discussed. Finally, further resolution improvement is achieved through the use

Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna

open access: yes, 2017
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

Direction finding for an extended target with possibly non-symmetric spatial spectrum [PDF]

open access: yes, 2004
We consider the problem of estimating the direction of arrival (DOA) of an extended target in radar array processing. Two algorithms are proposed that do not assume that the power azimuthal distribution of the scatterers is symmetric with respect to the ...

AN EIGEN-APPROACH FOR JOINT ESTIMATION OF DIRECTION-OF-ARRIVAL AND FREQUENCY OF AN UNKNOWN NUMBER OF SIGNALS

open access: yesJordanian Journal of Computers and Information Technology, 2020
An accurate method for estimating the direction-of-arrival (DOA) jointly with the frequencies of an unknown number of source signals is proposed using the Eigen-approach. Using the minimum eigenvalues of the autocorrelation matrices produces both the DOA
