摘要： A method of vehicle navigation includes controlling a phased array radar to search for an object within a first field of view and receiving a first direction, having a first direction resolution, and a first range, having first range resolution, of the object from the phased array radar. The method includes controlling a camera to search for the object based on the first direction and the first range within a second field of view that is smaller than the first field of view, and receiving a second direction of the object from the camera, wherein the second direction has a second direction resolution that is finer than the first direction resolution. The method includes outputting at least one of the second direction or the first range, and navigating the vehicle based on the at least one of the second direction or the first range.

摘要： A sense and avoid (SAA) module of a vehicle may receive a signal indicating a value of an environmental parameter. Additionally, the SAA system determines, based on the value of the environmental parameter, confidences value for a first and a second sensor group. The SAA system is configurable to determine a depth of an object based on signals from the first sensor group and is also configurable to determine the depth of the object based on signals from the second sensor group. The SAA system may determine, based on the depth of the object determined based on the signals from the first sensor group, the confidence value for the first sensor group, the depth of the object determined based on the signals from the second sensor group, and the confidence value for the second sensor group, a final 3-dimensional position of the object.

摘要： A system for tracking a vehicle includes a transceiver configured to receive a first signal including first surveillance data from the vehicle at a first time, and receive a second signal from the vehicle at a second time. The system further includes processing circuitry configured to determine a first location and a first course of the vehicle at the first time based on the first surveillance data, and determine a change in power level from the first signal to the second signal. The processing circuitry is further configured to predict a maneuver for the vehicle based on the first location, the first course, and the change in power level from the first signal to the second signal.

摘要： This disclosure is directed to systems and methods for generating outputs based on collected aircraft maneuver data. In one example, a system is configured to collect surveillance data from one or more aircraft. The system is further configured to identify, from the collected surveillance data, aircraft maneuver data indicative of maneuvers of the one or more aircraft. The system is further configured to store the aircraft maneuver data in a data store. The system is further configured to perform one or more analyses of the stored aircraft maneuver data in the data store. The system is further configured to generate an output based on the one or more analyses of the stored aircraft maneuver data.

摘要： The present disclosure provides computer vision systems and methods for an aircraft. The computer vision systems and methods identify a runway based on video frame data from a camera mounted to the aircraft, extract runway pixel positions associated with the runway, determine the aircraft position in a real world coordinate frame based on the pixel positions, the aircraft position including an aircraft lateral position and an aircraft elevation, receive predefined aircraft position data and go-around rules for a compliant approach to the runway, calculate an aircraft position deviation based on the aircraft position and the predefined aircraft position data, determine whether the aircraft position deviation is in conformance with the go-around rules, and output an indication of conformity with the go-around rules.

摘要： Disclosed are methods, systems, and computer-readable medium for facilitating remote user airspace communication. For instance, the method may include: connecting with a user device associated with and remote from a first vehicle in a shared air traffic control sector; receiving voice communication data from at least one of the user device, a second vehicle in the shared air traffic control sector, and an air traffic control station in the shared air traffic control sector; generating analog data or digital data based on the received voice communication data; determining a recipient for the generated analog data or generated digital data in the shared air traffic control sector; transmitting the generated analog data or generated digital data to the recipient; and terminating the connection with the user device as the first vehicle leaves the shared air traffic control sector.

摘要： Systems and methods for calibrating a synthetic image on an avionic display. The method includes receiving a synthetic image frame generated by an avionic display system and a sensor image frame from a forward-facing onboard sensor system. Object recognition is performed on the sensor image frame to generate a first search region for a first Federal Aviation Administration (FAA) marking, defined as a first search region-FAA marking pair. The sensor image frame and the first search region-FAA marking pair are processed using a deep learning method (DLM) to determine for the first FAA marking of the first search region-FAA marking pair, each of: a position deviation calculation, an orientation deviation calculation, and a synthetic image distortion factor. The synthetic image frame is then updated and rendered in accordance with the position deviation calculation, the orientation deviation calculation, and the synthetic image distortion factor, thereby calibrating the synthetic image frame.
