Processing of Crowdsourced Observations of Aircraft in a High Performance Computing Environment [PDF]
, 2020 As unmanned aircraft systems (UASs) continue to integrate into the U.S. National Airspace System (NAS), there is a need to quantify the risk of airborne collisions between unmanned and manned aircraft to support regulation and standards development. Both regulators and standards developing organizations have made extensive use of Monte Carlo collision ...

Sensitivity of Single-Pulse Radar Detection to Aircraft Pose Uncertainties [PDF]
arXiv, 2022 Mission planners for aircraft that operate in radar detection environments are often concerned the probability of detection. The probability of detection is a nonlinear function of the aircraft pose and radar position. Current path planning techniques for this application assume that the aircraft pose is deterministic.
