Abstract
This paper presents results from one of the few existing

outdoor measurement campaigns for UWB.

We specifically focus on scenarios applicable for "infostations," where

large amounts of data can be downloaded to a user within a limited amount of time.



We describe the measurement setup, and present a novel

high-resolution algorithm that allows the extraction of the scatterer's positions.

Measurement data is extracted using eight meter

uniform linear virtual array where incoming front waves are spherical,

and thus allowing for high-precision location of the scatterers.

Insight is given on how these components can be tracked in the impulse... (More)
This paper presents results from one of the few existing

outdoor measurement campaigns for UWB.

We specifically focus on scenarios applicable for "infostations," where

large amounts of data can be downloaded to a user within a limited amount of time.



We describe the measurement setup, and present a novel

high-resolution algorithm that allows the extraction of the scatterer's positions.

Measurement data is extracted using eight meter

uniform linear virtual array where incoming front waves are spherical,

and thus allowing for high-precision location of the scatterers.

Insight is given on how these components can be tracked in the impulse response

for a spatially varying terminal.



We then cluster the detected components, and investigate how the angular power variations of a

given scatterer are correlated with the power variations of the other scatterers

belonging to the same cluster. This results in the definition of the clusters'

angular radiation pattern.

Further sample

measurements show how obstacles obstruct the line-of-sight component; a

phenomenon that we describe mathematically by "shadowing regions," and

compare these measurements with the theoretical results predicted by diffraction theory. (Less)
