Constraints implementation for IQML and mode direction-of-arrival estimators
(2000-12-01)
The iterative quadratic maximum likelihood IQML and the method of direction estimation MODE are well known high resolution direction-of-arrival DOA estimation methods. Their solutions lead to an optimization problem with ...

Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
(Elsevier BVAmsterdam, 2012-01)
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or ‘multiplets’) which exhibit a correlation between arrival direction ...
Interpretation of angle-of-arrival measurements in the lower atmosphere using spaced antenna radar systems
(American Geophysical Union, 1998-05)
On the basis of scattering theory, we present four different contributions to angle-of-arrival (AOA) measurements using spaced antenna (SA) radar systems. We show that the measurement of the scattering parameters is needed ...
Protandria e seu impacto sobre a reprodução de uma ave migrante intra-tropical
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE ZOOLOGIAPrograma de Pós-Graduação em ZoologiaUFMG, 2021-08-13)
Introduction: Migratory birds annually face a costly journey during the breeding season. The arrival time in breeding grounds is associated with these costs and also with important consequences for individual fitness. ...
