摘要： A millimeter or mm-wave system includes transmission of a millimeter wave (mm-wave) radar signal by a transmitter to an object. The transmitted mm-wave radar signal may include at least two signal orientations, and in response to each signal orientation, the object reflects corresponding signal reflections. The signal reflections are detected and a determination is made as to location of the object.

摘要： A weather radar with a transmission antenna array that outputs a high aspect ratio FMCW transmission beam that illuminates an area in the field of regard in elevation and may be electronically scanned in azimuth. The weather radar includes a receive array and receive electronics that may receive the reflected return radar signals and electronically form a plurality of receive beams that may be used to determine characteristics of the area in the field of regard. The receive beams may be used to determine reflectivity of weather systems and provide a coherent weather picture. The weather radar may simultaneously process the receive signals into monopulse beams that may be used for accurate navigation as well as detection and tracking of objects, such as birds, aircraft, UAVs and the like.

摘要： A radar system to detect and track objects in three dimensions. The radar system including antennae, transmit, receive and processing electronics is all in a small, lightweight, low-cost, highly integrated package. The radar system uses a wide azimuth, narrow elevation radar pattern to detect objects and a Wi-Fi radio to communicate to one or more receiving and display units. One application may include mounting the radar system in an existing radome on an aircraft to detect and avoid objects during ground operations. Objects may include other moving aircraft, ground vehicles, buildings or other structures that may be in the area. The system may transmit information to both pilot and ground crew.

摘要： A transponder system that is adapted to be positioned in an aircraft includes a transponder that is adapted to transmit information pertaining to the aircraft in which the transponder is positioned includes at least one receiver that is adapted to receive information including information pertaining to another aircraft. The receiver(s) is adapted to receive different types of data on multiple different frequencies. A display, which may be integral with the system housing or remotely mounted, is adapted to display (i) information received by said receiver and/or (ii) information to guide user input selection of information transmitted by said transponder. The housing houses the transponder, the receiver and, in one embodiment, the display. The existing transponder in the aircraft can be removed thereby leaving an opening in the aircraft and the transponder installed in the opening.

摘要： An RF congestion monitoring system and method is provided. In one or more examples, the RF congestion monitoring system can include a modified aircraft transponder capable of receiving signals associated with Air Traffic Control and Traffic Collision Avoidance Systems, analyzing the received signals to determine the presence on one or more events occurring in the received signals, and generating an event count that identifies the types of signals associated with the events being received. A processor can receive the generated event count and based on the received count can calculate a transponder occupancy percentage metric indicative of the amount of RF congestion in a given air space. In one or more examples, the modified transponder can be configured to receive various radar signals in the 1030 and 1090 MHz frequency signal bands and process those signals to determine the amount of RF congestion in the airspace.

摘要： A system and method for identifying slow-moving and smaller flying objects using one or more radar based sensors is provided. In one or more examples, a radar system can be configured to generate plot data corresponding to flying objects in a given airspace. A tracker can be configured to receive the plot data, and can be configured to generate one or more tracks. The one or more tracks generated by the tracker can then be inputted into a classifier that is configured to distinguish unmanned aerial vehicle (UAV) traffic from birds that are flying in the airspace. In one or more examples, the classifier can generate an N-dimensional hypercube, with each dimension of the hypercube pertaining to a specific attribute of the flying objects. Each track can be converted into a data point within the hypercube and the data points can be clustered to determine whether the track belongs to a bird or a UAV.

摘要： Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network entity for wireless communications can transmit wide sensing signal beams in different directions to detect a target. The network entity can detect the target with one or more of the wide sensing signal beams. The network entity can transmit a narrow sensing signal beam in a direction towards the target to track the target, after the target has been detected. The network entity can further increase a power of the narrow sensing signal beam to provide energy to the target.

摘要： A system for providing integrated detection and deterrence against an unmanned vehicle including but not limited to aerial technology unmanned systems using a detection element, a tracking element, an identification element and an interdiction or deterrent element. Elements contain sensors that observe real time quantifiable data regarding the object of interest to create an assessment of risk or threat to a protected area of interest. This assessment may be based e.g., on data mining of internal and external data sources. The deterrent element selects from a variable menu of possible deterrent actions. Though designed for autonomous action, a Human in the Loop may override the automated system solutions.

摘要： Disclosed are methods and systems for providing millimeter wave assisted vehicle navigation. A method may include generating a frequency-modulated continuous wave (FMCW) signal, transmitting the FMCW signal as radio waves by a plurality of radar transmitters each having a beam direction, receiving reflected radio signals by a corresponding plurality of receivers, and determining individual beam velocities of the vehicle in each of the beam directions. The method may further include combining the individual beam velocities; generating a body velocity vector based on the combined individual beam velocities; combining input from the radar signal processor and a previous known vehicle position; and based on the combined input, providing real-time position and velocity information for the vehicle.
