Sionna ray tracing vs. real-world measurements: Signal strength comparison in rural scenarios with foliage

This dataset contains received signal strength (RSS) simulation results
generated using NVIDIA Sionna's ray tracing, along with real-world
UAV-based measurements collected at the NSF AERPAW testbed. The UAV
follows a predefined trajectory in a rural environment, transmitting
signals to five ground-based towers equipped with dual-channel USRP B210
devices. Corresponding ray tracing simulations are conducted using
identical trajectory and transceiver settings. The dataset includes three
main components: (1) raw GPS and RSS measurements, (2) ray tracing
simulation outputs, and (3) post-processed data aligned for direct
comparison. MATLAB scripts are provided to support trajectory
visualization, RSS calibration, and comparative analysis. This dataset
enables studies in RF propagation modeling, validation of ray tracing
simulations, and rural coverage analysis for UAV communication systems.
