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.
