摘要
This research aims at developing methods to meet safety targets for sense and avoid (SAA) sensors of unmanned aircraft systems (UAS) through integrity and continuity risk evaluation. This paper builds upon previous work that considered a constant-velocity aircraft encounter model with a 2D analysis. This study refines this model by accounting for intruder aircraft accelerations due to pilot actions, such as changes in thrust. These methods can determine the acceptability of a sensor or set of sensors. A 3D sensitivity analysis of intruder trajectories evaluates the impact on integrity and continuity of sensor noise, range, and sample interval. The methods described in this research can be used to set potential SAA sensor requirements for UAS integration into the National Airspace System.
