Following the increasing popularity of unmanned aerial vehicles (UAVs) for remote sensing applications, the reliable operation under a number of various radio wave propagation conditions is required. Assuming common outdoor scenarios, the presence of

2021 International Symposium ELMAR.
The automotive industry is progressively focusing on autonomous driving systems, and there are two main reasons behind that: first, the amount of legislation related to autonomous vehicles is gradually increasing, and second, the OEMs continuously se

The quantification of wet antenna attenuat-ion (WAA) represents one of the major uncertainties in rainfall retrieval from commercial microwave links (CMLs). We propose identifying WAA distribution and upper limits based on rainfall climatology withou

International audience; This paper presents a new model for scattering from tree canopies based on a modified physical optics approach. In this way, propagation through a canopy is accounted for by respecting the complex propagation constant, which c

In this study, a new composite channel model for land mobile satellite (LMS) systems under tree shadowing is proposed utilising the inverse Gaussian (IG) distribution to model the shadowing component. Using the experimental data of received power und

GNSS systems present an important challenge to the propagation modeler in that the requirements are different from those in communication systems: we are still interested in wideband modeling but the aim is knowing in much grater detail the arrangeme
