Methods of direction-of-arrival
[1991] IEEE Pacific Rim Conference on Communications, Computers and Signal Processing Conference Proceedings, 2002The direction-of-arrival (DOA) problem is of interdisciplinary interest, and a number of algorithms have been developed for its solution. These include beamforming, maximum-likelihood, least squares error modeling, and signal and noise subspace methods. A unifying development of these algorithms is presented. >

Multiple target direction of arrival tracking
IEEE Transactions on Signal Processing, 1995A new algorithm is presented for estimating the directions of arrival of signals from an unknown number of moving signal sources. The parameter space is a countable union of Cartesian products of the torus, each product space corresponding to a different number of signals reaching the sensor array. A Bayesian posterior probability measure is defined on

Practical direction-of-arrival system evaluation
2015 IEEE Radar Conference, 2015A system-level, performance evaluation of a direction-of-arrival (DOA) receiver is presented to show that exclusively optimising a single processing step can produce poor overall results. Monte-Carlo simulations of DOA receiver systems with different receiver architectures, integration methods and DOA algorithms are presented and evaluated.

Compressive wideband direction of arrival estimation
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015Compressive Sampling (CS) has recently emerged as a groundbreaking technique which reconstructs the sparse signal using samples taken below Nyquist sampling frequency (sub-Nyquist samples). In this paper we consider to estimate the Direction of Arrival (DOA) of wideband signals using sub-Nyquist samples.

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.

Decentralized Direction of Arrival Estimation
2017Direction-of-arrival (DOA) estimation using partly calibrated arrays composed of multiple subarrays is employed in various practical applications, such as radar, sonar, and seismic exploration. The state-of-the-art DOA estimation algorithms require the measurements of all sensors to be available at a processing center (PC).

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,

Direction of Arrival Model for Multipath
3rd International Conference on Electrical, Electronics, Engineering Trends, Communication, Optimization and Sciences (EEECOS 2016), 2016This paper attempts to model the multipath phenomenon on a sea surface, with primary emphasis on the DOA. The model in this paper considers parameters viz. height of target, height of radar, target range etc., The results of this paper discusses effects of height of target, height of radar, beam width of antenna, slant range of target and the DOA on ...
