Direction of arrival estimation in partly calibrated time-varying sensor arrays
We consider the direction finding problem in time-varying arrays composed of identically oriented subarrays displaced by unknown vector translations. A new eigenstructure-based estimator is proposed for such a class of partly calibrated sensor arrays.
متن کاملNon-Coherent Direction of Arrival Estimation via Frequency Estimation
This letter investigates the non-coherent Direction of Arrival (DOA) estimation problem dealing with the DOA estimation from magnitude only measurements of the array output. The magnitude squared of the array output is expanded as a superposition of some harmonics. Hence, a frequency estimation approach is used to find some nonlinear relations between DOAs, which results in inherent ambiguities...
متن کاملDirection Finding With Partly Calibrated Uniform Linear Arrays
A new method for direction finding with partly calibrated uniform linear arrays (ULAs) is presented. It is based on the conventional estimation of signal parameters via rotational invariance techniques (ESPRIT) by modeling the imperfections of the ULAs as gain and phase uncertainties. For a fully calibrated array, it reduces to the conventional ESPRIT algorithm. Moreover, the direction-of-arriv...
متن کاملDirection-of-arrival Estimation of Wideband Sources Using Sensor Arrays
To my family. My father and mother. Especially, to my beloved wife Ji-Hyun and my precious Catherine. iii ACKNOWLEDGEMENTS When I came to Georgia Tech, I used to imagine the moment when I graduate and thought that it would take forever to finish my graduate work. Since then, five years passed fast and I have finished my thesis. While I was writing this thesis, I could not help thinking that it ...
متن کاملDirection of Arrival Estimation and Localization Using Acoustic Sensor Arrays
Sound source localization has numerous applications such as detection and localization of mechanical or structural failures in vehicles and buildings or bridges, security systems, collision avoidance, and robotic vision. The paper presents the design of an anechoic chamber, sensor arrays and an analysis of how the data acquired from the sensors could be used for sound source localization and ob...
