Direction of arrival (DOA) parameter estimation with the SAGE algorithm

Signal Processing, 2004
In 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 ...

Multipath Separation-Direction of Arrival (MS-DOA) With Genetic Search Algorithm for HF Channels [PDF]

Advances in Space Research, 2009
Direction-of-Arrival (DOA) defines the estimation of arrival angles of an electromagnetic wave impinging on a set of sensors. For dispersive and time-varying HF channels, where the propagating wave also suffers from the multipath phenomena, estimation of DOA is a very challenging problem.

Improved maximum likelihood spectrum for direction of arrival (DOA) estimation

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
A 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).

A SYSTOLIC ARCHITECTURE FOR CAPON'S DIRECTIONS-OF-ARRIVAL (DOA) ESTIMATION METHOD

Parallel Algorithms and Applications, 1993
In this paper, a systolic array architecture is designed for the parallel implementation of Capon's direction-of-arrival estimation method in array signal processing. The architecture uses the QR decomposition on the data matrix to compute Capon's angular spectrum. The systolic array employs N(N + l)/2 + N processing elements (PEs).

Adaptive Filtering Algorithm for Direction-of-Arrival (DOA) Estimation With Small Snapshots

Digital Signal Processing, 2019
Abstract The direction-of-arrival (DOA) estimation problem with a few noisy snapshots can be formulated as a problem of finding a joint sparse representation of multiple measurement vectors (MMV), and some algorithms based on compressive sensing (CS), such as the joint l 0 approximation DOA (JLZA-DOA) and Multiple Snapshot Matching ...

Direction of Departure (DOD) and Direction of Arrival (DOA) Estimation in MIMO Radar With Reduced-Dimension MUSIC

IEEE Communications Letters, 2010
This letter discusses the problem of direction of departure (DOD) and direction of arrival (DOA) estimation for multi-input multi-output (MIMO) radar, and derives a reduced-dimension multiple signal classification (MUSIC) algorithm therein. The proposed algorithm, which only requires one-dimension search, can avoid the high computational cost within ...

DOA(Direction of Arrival) with array antennas based on MOM

2010 IEEE Antennas and Propagation Society International Symposium, 2010
It's an important issue that estimation of signal direction for radar or communication system. And it was researched for military and commercial. Generally, it's a method that estimate to direction of signal by use each signal of array sensors. It called to DOA(Direction Of Arrival). For basically, there are Beamforming, Capon, Linear-prediction method.
