Virtural receiving array (VRA) method for direction of arrival (DOA) estimation
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012Using the data from a signal-element receiver on a moving Unmanned Arial Vehicle (UAV), this paper introduces a VRA method to obtain the data that can be used in the Direct Data Domain (D3) method for the signal DOA estimation.

Direction of Arrival (DOA) Estimation Using Electrically Small Tuned Dipole Antennas
IEEE Transactions on Antennas and Propagation, 2006We present a methodology for the direction of arrival (DOA) estimation using the induced voltages that are measured at the loads connected to electrically small tuned dipole antenna arrays illuminated by the signal of interest (SOI). The matrix pencil method is applied directly to the induced voltages to estimate the DOA of the various signals.

Comparison of conventional and subspace based algorithms to estimate Direction of Arrival (DOA)
2016 International Conference on Communication and Signal Processing (ICCSP), 2016The Direction of Arrival (DOA) technology and researches are evolving areas in array signal processing. Biomedicine, sonar, radar, seismology, astronomy communication and earthquake widely use this estimation. We receive an incoming wave by sensing an array or a set of arrays, this sensed wave can be processed to derive many related estimation ...

Performance enhancement of aperture antennas used for estimation of Direction of Arrival (DOA)
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this paper, we propose a method based on signal processing techniques to improve the performance of aperture antennas, such as a parabolic reflector, used to estimate the Direction of Arrival (DOA) of a signal. Three signal processing algorithms are investigated, including the correlation method, which is used to make an initial estimate of the ...

Direction of arrival (DOA) estimation system using 3D printed Luneburg lens
2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES), 2016A novel direction of arrival (DOA) estimation system based on a broadband 3D printed Luneburg lens is reported in this paper. Using the property of a Luneburg lens that the focus point of an incident plane wave is at the opposite side on the surface of the lens, 36 diode detectors with 10 degree spacing are mounted around the surface of a 3D printed ...

IEEE Transactions on Vehicular Technology, 2002
An effective technique in estimating the directions of arrival (DOAs) of incoming signals using three orthogonal sensors is proposed. The channel model with multipath transmissions for code-division multiple access (CDMA) users whose signals are modulated with binary phase-shift keying (BPSK) is used.

Comparative Study of Wideband Subspace Direction of Arrival (DOA) estimation methods
The Journal of the Acoustical Society of America, 2008Signal subspace Methods like ESPRIT, MUSIC and MATRIX PENCIL, provides high resolution Direction Of Arrival (DOA) estimation in comparison to traditional Delay and Sum and Capon methods, which are limited by sensor spacing. However underwater Acoustics signals are inherently wideband in nature and most of these Subspace methods works on narrowband ...

Mutual coupling effects correction in microstrip arrays for direction-of-arrival (DOA) estimation
IEE Proceedings - Microwaves, Antennas and Propagation, 2002The presence of mutual coupling severely degrades the performance of an adaptive array. A simple method based on obtaining an N/spl times/N coupling matrix, C, to compensate for the coupling effects in direction-of-arrival (DOA) estimation algorithms is presented.
