Unmanned Aircraft Collision Avoidance: Technology Assessment and Evaluation Methods

Collision avoidance is emerging as a key isuees for UAS access to civil airspace. Numerous technologies are being explored in the community to develop a solution for collision avoidance. The problem is multi-dimensional and needs to be addressed at the system level. Requirements for collision avoidance capabilities are complex and vary with the intended airspace of operation and the corresponding potential hazards. The appropriate mitigations are likely to be equally complex. A suite of several sensor technologies is likely to be required in order to address the full set of collision hazards. The intent of this paper is to present a perspective on the challenges associated with UAS collision avoidance from a civil aviation perspective and to present results from some of MITRE's research addressing collision avoidance technologies and systems performance analysis.
