Multi-intruder aircraft, multi-sensor tracking system

The National Airspace is evolving with the introduction of new types of aircraft and increased surveillance and safety requirements. Detect and Avoid (DAA) systems are designed to meet these requirements for both cooperative and non-cooperative air traffic. In this paper, we describe the Honeywell Tracking System (HTS) which provides DAA systems with accurate and smooth tracks for cooperative and non-cooperative intruder aircraft relative to an ownship aircraft. The HTS uses a combination of cooperative and non-cooperative sensors to track thirty intruder aircraft within one framework in real-time. We demonstrate the performance of the HTS using the results of two flight tests with cooperative and non-cooperative intruder aircraft.
