To allow for routine operation in the NAS, Navy UAS platforms will be required to have a certified Air-Based Sense and Avoid (AB-SAA) system to provide collision avoidance against non-cooperative threats. The choosen AB-SAA sensor is an air-to-air radar system being developed by RDRTec. This effort will 1) optimize tracker design developed in Phase 1 that accurately characterize the tracker errors when predicting the target s future position, 2) develop threat determination and suggested avoidance maneuver algorithms using tracker and threat maneuvers uncertainties, 3)Prove the performance using Monte-Carlo simulation that uses Fire Scout sensor performance models, dynamics models, and stressing scenarios, 4)Develop real time code for SAA system and 5) Optionally, demonstrate in end-to-end HWIL simulation and flight tests.
