This work addresses the growing need for Electromagnetic Compatibility (EMC) studies in aviation, driven by the coexistence of legacy avionics systems with newer radio services and the long life cycles of aircraft technologies. Because real aircraft are difficult to access for measurements and in-flight measurement campaigns are complex, the study focuses on laboratory-based simulation of avionic radio channels.
Two main approaches are investigated. First, the communication channel inside an aircraft cabin is characterized using a 1:10 scale aluminum fuselage model. Cabin equipment is represented by simple absorbing structures. Antennas operating between 20 GHz and 67 GHz are developed to perform measurements. By varying the transmitter position and the scattering environment, field samples are collected and used to build a statistical channel model. The model is validated by comparing parameters such as the quality factor and decay time with values reported in the literature.
Second, the thesis examines line-based simulation of dynamic propagation channels using software-defined radio (SDR). The method reproduces key channel modulation effects, demonstrated with a navigation signal example. This approach allows researchers to study how receiver parameters influence error evaluation and to estimate cumulative errors caused by disturbances while accounting for both channel dynamics and receiver behavior.
Overall, the thesis presents laboratory methods for characterizing and simulating aviation propagation environments, enabling preliminary investigations without requiring full-wave electromagnetic simulations or measurements on real aircraft.
