Investigating the use of ray tracing for signal-level radar simulation in space monitoring applications: a comparison of radio propagation models
… an open-source, ray-traced radar simulator that models the interactions between spaceborne targets and terrestrial radar systems. This utilises a ray-tracing algorithm to simulate the effects of debris size, shape, orientation, and material properties when computing radar signals in a typical …

A Technique for Evaluating the Uncertainties in Path Loss Predictions Caused by Sparsely Sampled Terrain Data
Radio propagation models provide an estimate of the power loss in a communication link caused by the surface of the ground, atmospheric refraction, foliage, and other environmental factors. Many of the models rely on digital topographic databases to provide information about the terrain, and …

Large-scale and high-fidelity wireless network simulation and emulation
… physical layer fidelity: we use sophisticated radio propagation models such as ray-tracing, validated by an anechoic chamber. 2) High application functional fidelity: we allow unmodified and compiled application code to run inside our system, minimizing the modeling error of software behavior. …

Indoor localization using place and motion signatures
… indoor localization depend on either simple radio propagation models or exhaustive, costly surveys conducted by skilled technicians. These methods are not satisfactory for long-term, large-scale positioning of mobile devices in practice. This thesis describes two approaches to the indoor …
