Gps Direction Finding
GNSS receivers provide position information in a convenient way. However, additional orientation information cannot be fulfilled directly by a single antenna receiver up to now. This paper describes an approach for determination of orientation using a single GNSS receiver based only on its own static observations. As estimable base quantity, satellite positions are used as a reference in the mo...
متن کاملDecoupled direction finding: detection
Antenna arrays are likely to be an important feature of future mobile communication systems. With an antenna array, mobile users can be separated by a spatial filtering procedure allowing several users on the same carrier frequency. The uplink part (mobile to base) not only can, but is better solved without using any spatial knowledge in terms of direction of arrival (DOA). However, DOA estimat...

The area of sensor array processing has attracted considerable interest in the signal processing community. The focus of this work has been on high resolution Direction Of Arrival (DOA) estimation algorithms that detect and locate aircrafts using radar systems. These algorithms exploit the fact that an electromagnetic wave that is received by an array of antenna elements reaches each element at...
متن کاملGenetic Algorithms in Direction Finding
Passive receiving systems are used to intercept emissions of interest, both communication and Radar, and to measure their characteristic parameters in order to classify and possibly identify them. Direction of Arrival (DOA) is one of the most important parameters to be measured, as it can yield a localization fix by means of triangulation (if more receivers are dislocated on the area), or howev...
متن کاملAcoustic correlated sources direction finding in the presence of unknown spatial correlation noise
In this paper, a new method is proposed for DOA estimation of correlated acoustic signals, in the presence of unknown spatial correlation noise. By generating a matrix from the signal subspace with the Hankel-SVD method, the correlated resource information is extracted from each eigen-vector. Then a joint-diagonalization structure is constructed of the signal subspace and basis it, independent...
