Radar Sense And Avoid (SAA) Processing

To allow for routine operation in the NAS, Navy UAS platforms will be required to have an FAA certified Air-Based Sense and Avoid (ABSAA) system. This will compliment the Ground-Based Sense and Avoid (GBSAA) system which together form a layered surveillance strategy for UAS collision avoidance. The inner most layer is the Air-to-Air Radar Subsystem (AARSS)which is the key sensor in the ABSAA system as it directly addresses the very difficult problem of non-cooperative collision threats. Radar is the sensor of choice due to its all weather capabilities as well as its ability to directly measure range, range-rate and angle using pulsed-Doppler techniques. This investigation is focused on developing a capable and cost-effectible SAA AARSS on the Fire Scout on the way to FAA certification.
