摘要： Embodiments are generally directed to anti-spoofing techniques for satellite navigation systems. In general, the anti-spoofing techniques use codeless or semi-codeless tracking of encrypted satellite signals to generate measurements that can be used to perform consistency checks to received non-encrypted signals. The consistency checks will detect if the non-encrypted signal is a genuine satellite signal or a spoofing signal.

摘要： A registration authority (RA) server registers unmanned aerial vehicles (UAVs) and their owners/operators (O/O). A UAV is maintained in a flight lock state until a flight plan request from the O/O is approved by the RA, which sends an key-signed approval to unlock the UAV's flight lock. The RA server evaluates a UAV's proposed flight plan based on the attributes of the O/O and UAV, the location and time of the requested flight plan, and a set of flight rules and exclusion zones that are developed in view of privacy assurance, security assurance, flight safety assurance, and ground safety assurance. The flight plan key-signed approval supplied to the UAV by the RA server specifies an inclusion zone that corresponds to a flight plan trajectory to be followed. Once in flight, the UAV maintains real-time knowledge of its position and time to ensure its flight remains within the approved inclusion zone.

摘要： A computer simulates flight routes for simulated airborne transmitters across a spatial region divided into unit area tiles and over time based on actual aircraft flight plan data. The computer determines transmitter counts per tile per time interval based on the flight routes and assigns transmit parameters, including transmit message rates, to the transmitters. The computer determines transmit message rates per tile based on the transmitter counts and the transmit parameters. The computer generates, for a simulated receiver, an antenna pattern covering at least some of the tiles, and converts the transmit message rates of the covered tiles to a total effective receive message rate of interfering messages at the receiver. The computer determines a probability of successful detection of a desired message among the interfering messages at the receiver based on the effective receive message rate.

摘要： Image navigation of an input image by edge registration proceeds by generating a reference image kernel in which edges of a reference image are embraced by borders. Image intensities of the reference image kernel internal to the borders increase with decreasing distance from the edges. A registration score is computed by cross-correlating the image intensities of the reference image kernel with image intensities in the input image. A feature exists in the input image when the registration score meets a registration criterion.

摘要： A method of detecting a dynamic weather event includes the steps of: (a) receiving video images of a scene from a camera; (b) dividing each of the video images into multiple regions, in which a region is defined by a range of distances from the camera to objects in the scene; (c) selecting a region; and (d) segmenting the selected region into a plurality of three-dimensional (3D) image patches, in which each 3D image patch includes a time-sequence of T patches, with each patch comprised of N×M pixels, wherein N, M and T are integer numbers. The method also includes the following steps: measuring an image intensity level in each of the 3D image patches; masking 3D image patches containing image intensity levels that are above a first threshold level, or below a second threshold level; and extracting features in each 3D image patch that is not discarded by the masking step. Based on the extracted features, the method makes a binary decision on detecting a dynamic weather event.

摘要： A panoramic camera system includes a plurality of camera units mounted in a common, e.g., horizontal, plane and arranged in a circumferential array. Each camera unit includes one or more lenses for focusing light from a field of view onto an array of light-sensitive elements. A panoramic image generator combines electronic image data from the multiplicity of the fields of view to generate electronic image data representative of a first 360-degree panoramic view and a second 360-degree panoramic view, wherein the first and second panoramic views are angularly displaced. A stereographic display system is provided to retrieve operator-selectable portions of the first and second panoramic views and to display the user selectable portions in human viewable form. In a further aspect, a video display method is provided.

摘要： A technique for determining the position of a mobile device includes receiving messages from respective mobile reference devices. Each of the messages is broadcast beginning at one of several predetermined message start opportunity (MSO) times that have known timings relative to a reference time. Each of the messages contains a MSO value identifying the MSO time at which transmission of the message started. The MSO value is used to determine the time of transmission of each of the messages received at the mobile device, and the position of the mobile device is determined via multi-lateration. According to another approach, the mobile device receives a set of ADS-B messages from a respective set of mobile reference devices. The time of transmission of each of the ADS-B messages is supplied in the ADS-B message itself or in a subsequent message and used to determine the position of the mobile device.

摘要： A focal plane array (FPA) imaging sensor includes an array of multiple tuning cells disposed on a monolithic substrate, in which each tuning cell includes: (a) a tunable etalon disposed in the monolithic substrate, and (b) a THz detector assembly comprised of at least two antennae disposed in the monolithic substrate. The THz detector assembly is disposed below the tunable etalon. Each tunable etalon includes a Fabry-Pérot interferometer comprised of upper and lower mirrors, spaced by a gap between the mirrors, the gap forming an etalon of the interferometer. The FPA imaging sensor may also be formed as a hybrid, in which portions of the tuning cells are fabricated separately from the THz detector assembly and aligned to each other. The lower mirrors may also be fabricated monolithically with the substrate and the upper mirrors may be formed separately and then aligned to the lower mirrors.
