Slant path attenuation of microwaves in vegetation is an important topic for mobile satellite services. Besides the frequency, the attenuation is influenced by the type of vegetation, its density, and the change of the foliage through the seasons. For many applications in this field more experimental data are requested. This study presents experimental results on attenuation in vegetation for slant...
With increasing utilization of satellite mobile services capacity shortage in respectively common frequency bands (L band) is to be expected. To enhance understanding of propagation channel characteristics at higher frequency bands (Ku/Ka band) an experiment with a mobile receiver, using narrow- and wideband test signals has been carried out. An airborne test platform has allowed to consider real...
The selection of the right power distribution architecture for a given application has a tremendous impact on the overall system in terms of efficiency, cost, reliability, fault tolerance and size. Moreover, with the increasing number of power sources, storage elements, different supply voltages and strong requirements imposed at system level, the selection of the appropriate architecture becomes...
This paper describes a parameterization software used for the generation of behavioral models of power converters. This tool eases the capture and generation of fast and accurate models based on the information provided by manufacturers and measures. The models incorporate many behavioral features and can be used at different levels in the analysis, design and verification of complete power distribution...
