Reflector Localization for Geometrical Modeling the Air-Ground Channel

Kurzfassung

In the air-ground propagation channel, multipath propagation severely affects the performance of the communications, navigation, and surveillance systems used in civil aviation. To gain a deeper understanding of the airground channel we are interested in the locations of objects causing multipath propagation. Therefore, in this paper we propose and experimentally validate an algorithm to localize reflectors causing multipath components based on channel sounding data collected using omnidirectional antennas. The algorithm relies on super-resolution parameter estimation and tracking as well as a localization algorithm. Using channel sounding data collected from flight trials we demonstrate the ability to accurately localize the reflectors causing multipath components.
