Maneuver Prediction and Avoidance Logic For Unmanned Aircraft System (UAS) Encounters with Non-Cooperative Air Traffic

Air-Borne Sense and Avoid (ABSAA) cooperative sensors like TCAS and ADS-B are non-developmental off-the-shelf items and as such their employment should be optimized to maximize their effect on levels of safety. The radar subsystem is a new construct whose role and employment has not been previously defined. In addition, the cost of the radar development and production costs are high and dependent on its assigned role and the associated performance requirements. As such a complete assessment of the Size Weight and Power (SWaP) and costs must be included in the establishment of safety requirements. Currently, the Navy is formulating the traceability between Air-Borne Sense and Avoid (ABSAA) radar subsystem and system requirements for UAS platforms including Triton and Fire Scout. This STTR builds on and is coordinated with that effort but focuses on a specific radar ABSAA subsystem, the Common Radar Automatic Collision Avoidance System (C-RACAS) in order to support its development schedule. C-RACAS is targeted for both the Fire Scout and Triton platforms.
