An Efficient 2-D DOA Estimation for a Cylindrical Conformal Array with Unknown Mutual Coupling

open access: yesInternational Journal of Antennas and Propagation, 2018
The limited space of a conformal array may lead to a serious mutual coupling effect, which will significantly affect the performance of direction of arrival (DOA) estimation algorithms.

Selective Range Iterative Adaptive Approach for High-Resolution DOA Estimation

open access: yesIEEE Access, 2019
In this paper, the problem of direction-of-arrival (DOA) estimation for a uniform linear array with single-snapshot observations is addressed. Two non-parametric DOA estimators are developed, which can be applied in any azimuth range with one snapshot ...

On Improvements of Cyclic MUSIC

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
Many man-made signals encountered in communications exhibit cyclostationarity. By exploiting cyclostationarity, cyclic MUSIC has been shown to be able to separate signals with different cycle frequencies, thus, to be able to perform signal selective ...

Joint DOA and TOA estimation method based on Pareto multi-task learning

open access: yes上海师范大学学报. 自然科学版
A joint estimation method for direction of arrival (DOA) and time of arrival (TOA) was proposed based on Pareto multi-task learning, which transformed the traditional multi-task learning problem into a multi-objective optimization problem for solution. A

Performance analysis of MUSIC for spatially distributed sources

open access: yes, 2014
In this paper, the direction of arrival (DOA) localization of spatially distributed sources impinging on a sensor array is considered. The performance of the well known MUSIC estimator is studied in presence of model errors due to angular dispersion of ...

DOA Estimation Based on Logistic Function for CD Sources in Impulsive Noise

open access: yesIET Signal Processing
To improve direction of arrival (DOA) estimation for coherently distributed sources under impulsive noise environments, a logistic-based adaptive factor is proposed to suppress the impulsive noise contained in the output signals of the array.
