Source number estimation using eigenspace in direction of arrival (DOA) estimate
OCEANS 2009-EUROPE, 2009A source number estimation using eigenspace is presented. It projects estimated covariance matrix of array signal into signal eigen subspace and noise eigen subspace respectively. Using the orthogonality between signal eigen subspace and noise eigen subspace, it is easy to differentiate the contribution of signal and noise by using the criterion value,

Improved maximum likelihood spectrum for direction of arrival (DOA) estimation
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003A variation of J. Capon's (1969) maximum-likelihood (ML) spectral estimation algorithm is described for calculating direction of arrival using a short linear array. The proposed modification involves altering the computed covariance spectral matrix by setting its lowest eigen value to a small, positive constant lambda '(min).

Direction of arrival (DOA) parameter estimation with the SAGE algorithm
Signal Processing, 2004In this study, we investigate the estimation of the relative delay, the azimuth and elevation angle and the complex amplitude of a known received signal with the space alternating generalised expectation (SAGE) maximisation algorithm. This optimisation algorithm is used to replace the high-dimensional optimisation procedure, necessary to compute the ...

Direction-of-Arrival (DOA) Estimation based on Spacetime-Modulated Metasurface
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019We introduce the concept of DOA estimation based on spacetime-modulated 2D-patch-array metasurface. Such a system, compared to conventional DOA estimators, offers the key advantage of requiring only one receiving antenna, with the metasurface placed in front of it.
