    Abstract: A system and method for tracking non-cooperative obstacles during operation of a vehicle is provided. The system may include a radar system, an optical sensor, and a processor. The radar system can be coupled to the vehicle and configured to scan a first airspace and generate radar information having a first resolution. The optical sensor can be coupled to the vehicle and configured to image a second airspace and generate optical information at a second resolution that is higher than the first resolution, where the second airspace is within said first airspace and includes a non-cooperative obstacle. The processor can be configured to identify the non-cooperative obstacle within the first airspace based at least in part on the radar information, and direct the optical sensor toward a location of the non-cooperative obstacle using the radar information.

    Abstract: A LIDAR system for vehicle operation that can operate in degraded visual environments (DVE) is described. The LIDAR system may use a spatial light modulator to find the phase conjugate of the DVE being traversed by the laser beam and cancel out the backscatter from the DVE, which allows the detection of extremely small numbers of directly reflected photons reflected by a target surface. If the target is not detected, the LIDAR is iteratively scanned to its maximum available depth of focus until the target is acquired. The LIDAR system is especially useful for autonomous landing of VTOL aerial vehicles in locations where the target landing spot is approximately known but cannot be directly visualized due to DVE media, such as smoke, dust, fog, or the like.

    Abstract: The present disclosure is directed to scanning radar reflector systems, methods, and apparatuses; even more particularly to a system, method, and apparatus for scanning and reflecting a radar beam transmitted by a radar transmitter onboard an aerial vehicle with radar reflectors equipped on unmanned aerial vehicles. The radar reflection system may include one or more unmanned aerial vehicles equipped with a one or more axis gimbal upon which a radar reflector is mounted. A user may position the unmanned aerial vehicle and the radar reflector to target a specific region for radar scanning.

    Abstract: An autonomous aerial system for delivering a payload to a waypoint. The autonomous aerial system may comprise an aerial vehicle to transport the payload to the waypoint and an onboard supervisory control system operatively coupled with the aerial vehicle. The aerial vehicle may be configured to navigate to the waypoint and to land at a designated touchdown zone within a landing zone at the waypoint. The onboard supervisory control system having a processor operatively coupled with a non-volatile memory device and a sensor package. The processor may be configured to generate flight control signal data based at least in part on data received via the sensor package, the sensor package configured to (1) dynamically sense and avoid obstacles along a flight route to the waypoint, and (2) perceive physical characteristics of the landing zone. The processor may be configured to autonomously navigate the aerial vehicle to the waypoint and to determine whether to touchdown at the designated touchdown zone based at least in part on physical characteristics of the designated touchdown zone perceived via said sensor package.

    Abstract: The subject disclosure relates to a simulation system having an aircraft, a local wireless transceiver, and a simulation computer. The aircraft may include an onboard wireless transceiver and a flight controller operatively coupled with an onboard sensor payload to perceive a physical environment and to generate position and pose data. The simulation computer may be configured to communicate wirelessly with the aircraft via the local wireless transceiver. In operation, the simulation computer may be configured to generate one or more virtual reality sensor inputs and to receive the position and pose data from the aircraft. The simulation computer can be configured to transmit the one or more virtual reality sensor inputs to the flight controller of the aircraft.
