SPHERICAL COVERAGE DUAL MODE SENSOR FOR UAS SEPARATION ASSURANCE

Proposed is a dual-mode sensor for use aboard unmanned aircraft for safe operation in the NAS that:1. Incorporates high resolution Millimeter Wave radar with high resolution Electro-Optical sensor.2. Achieves complete real time, full time spherical coverage around the UAS platform by employing two hemispherical dual mode sensors, one directed forward and one directed to the rear.[which exceeds the detection range and field-of-regard (FOR) for all nearby air platforms in FAA Regulation 7610.4 and other requirements from DOD/FAA documents].3. Utilizes multiple coherent transceivers.4. Meets SWaP and cost requirements for most UASs, including price (less than $3000 in quantity), size (less than 1 cubic feet), weight (less than 2 lb) and power (less than 10W).5. Leverages as needed the Automatic Dependent Surveillance Broadcast (ADS-B), which will be implemented by the FAA in the NAS.6. Considers aircraft that operate without ADS-B.7. Performs multiple functions; including autonomous detection, tracking, predicting of future track and specification of collision avoiding maneuvers.8. Is self-contained, with sensor capability combined with on-board computing and flight control system, yet can be operated with sense and avoid interoperability.
