Richtungsaufgelöste Kanalmodellierung und Systemstudien für Mehrantennensysteme in urbanen Gebieten
Das vorliegende Buch bietet eine umfassende Analyse des urbanen Mehrnutzer-MIMO-Funkkanals und stellt ein neuartiges geometrisch-stochastisches Kanalmodell für diesen Kanal vor. Besonderes Augenmerk liegt dabei auf der realistischen Modellierung der Zeitvarianz, Frequenz- und Richtungsselektivität sowie der Nutz- und Interferenzsignale im Netz. Zur Parametrierung und Verifikation des Modells werden Ray Tracing Simulationen sowie beidseitig richtungsaufgelöste Funkkanalmessungen eingesetzt

SIGNAL: Sar for Ice, Glacier and Global Dynamics
SIGNAL is an innovative earth exploration mission proposal
with the main objective to estimate accurately and repeatedly topography and topographic changes associated with mass change or other dynamic effects on glaciers, ice caps and polar ice sheets. Elevation measurements are complemented
with glacier velocity measurements, providing valuable additional information for a better understanding of the hydrology of glacierized basins and of the Arctic and Antarctic water cycle. SIGNAL is capable of monitoring all critical regions with a high spatial resolution and an adequate revisit time. This paper gives an overview about the actual mission design status and provides a brief description of the topography (DEM – digital elevation map) self-calibration strategy and the estimated global interferometric performance
SIGNAL - SAR for Ice, Glacier aNd globAL Dynamics - Mission Description Document
SIGNAL is an innovative earth exploration mission proposal with the main objective to estimate accurately and repeatedly topography and topographic changes associated with mass change or other dynamic effects on glaciers, ice caps and polar ice sheets. Elevation measurements are complemented with glacier velocity measurements, providing valuable additional information for a better understanding of the hydrology of glacierized basins and of the Arctic and Antarctic water cycle. SIGNAL is capable of monitoring all critical regions with a high spatial resolution and an adequate revisit time. The present document is a summary of the SIGNAL mission that has been proposed in response to the call for an Earth Explorer Opportunity Mission (issued by DLR in 2010). This document gives a concise description and overview of the SIGNAL mission

SIGNAL is an innovative earth exploration mission proposal with the main objective to estimate accurately and repeatedly topography and topographic changes associated with mass change or other dynamic effects on glaciers, ice caps and polar ice sheets. Elevation measurements are complemented with glacier velocity measurements, providing valuable additional information for a better understanding of the hydrology of glacierized basins and of the Arctic and Antarctic water cycle. SIGNAL is capable of monitoring all critical regions with a high spatial resolution and an adequate revisit time. The present document provides a preliminary and limited system functional specification of the SIGNAL mission that has been proposed in response to the call for an Earth Explorer Opportunity Mission (issued by DLR in 2010)
