Abstract: A radar system includes an antenna array including a plurality of antenna elements; and a transmitter portion coupled to the antenna array, the transmitter portion being configured to sequentially transmit a first transmit beam and a second transmit beam from a single pulse, the first transmit beam and second transmit beam being formed using the same aperture of the antenna array, wherein a skew angle of the first transmit beam is distinct from a skew angle of the second beam. Such radar system alternatively transmitting through subarrays and receiving each via the entire array and combining the signals such that the transmit and receive parts of one of two 2-way beams point in the same direction and the transmit and receive parts of the second 2-way beam point in the same direction and these directions are within a standard beamwidth of each other.

Abstract: A radar apparatus with a transmission antenna array that outputs a high aspect ratio frequency modulation continuous wave (FMCW) transmission beam that illuminates a large field of regard in elevation and may be both electronically and mechanically scanned in azimuth. The weather radar apparatus includes a receive array and receive electronics that may receive the reflected return radar signals and digitally 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 apparatus may simultaneously process the receive signals into monopulse beams that may be used for accurate navigation as well as collision avoidance.

Abstract: The antenna uses X Band frequencies for long-distance weather monitoring and W Band frequencies for imaging of terrain and obstacles, for use in a radar system in aircraft nose radome to operate effectively in a degraded visual environment. The antenna's feed structure includes concentrically positioned first and second horns. First and second rectangular waveguides are positioned on a cylindrical portion of the first horn, and at a first and second radial positions spaced 90 degrees apart. First and second coaxial cables respectively couple the first and second rectangular waveguides to a polarization converter, which launches linearly polarized waves received from each of the first and second coaxial cables to form a W-hand circularly polarized wave. The feed structure collects and disseminates W Band and X Band electromagnetic energy.

Abstract: A method, system and computer program product for emulating depth data of a three-dimensional camera device is disclosed. The method includes concurrently operating the radar device and the 3D camera device to generate training radar data and training depth data respectively. Each of the radar device and the 3D camera device has a respective field of view. The field of view of the radar device overlaps the field of view of the 3D camera device. The method also includes inputting the training radar and depth data to the neural network. The method also includes employing the training radar and depth data to train the neural network. Once trained, the neural network is configured to receive real radar data as input and to output substitute depth data.

Abstract: An advanced driver assistance system (ADAS) and method for a vehicle utilize a light detection and ranging (LIDAR) system configured to emit laser light pulses and capture reflected laser light pulses collectively forming three-dimensional (3D) LIDAR point cloud data and a controller configured to receive the 3D LIDAR point cloud data, convert the 3D LIDAR point cloud data to a two-dimensional (2D) birdview projection, detect a set of lines in the 2D birdview projection, filter the detected set of lines to remove lines having features that are not indicative of traffic signs to obtain a filtered set of lines, and detect one or more traffic signs using the filtered set of lines.

Abstract: A system and method for a multi-panel multi-function active electronically scanned array (AESA) radar operation receives radar commands from individual aircraft systems and segments a plurality of AESA panels fixed (at variable azimuth/elevation about the aircraft) into a plurality of subarrays to carry out each individual function commanded by the individual aircraft system. Dependent on aircraft status and phase of flight, the and individual AESA are designated for use and the subarrays are sized based on desired radar function at the specific phase of flight and specific threat associated with the phase. The system dynamically shifts the designated AESA, subarray size, beam characteristics, power settings, and function to enable multiple simultaneous function of the suite of AESA panels.

Abstract: An electronic device includes a plurality of radars and at least one processor. Each of the radars includes at least one transmitting antenna and a plurality of receiving antennas arranged as a two-dimensional array antenna. The processor converts the RF signal received by the receiving antennas into a ranging profile that records the distance between each of the receiving antennas and the target and the receiving intensity corresponding to the distance. The processor generates a voxel profile to indicate the relationship between the distance and the receiving intensity in three-dimensional space. The processor performs a point generation algorithm to generate a plurality of points in three-dimensional space according to the voxel profile and the receiving intensity threshold. The processor performs a cluster analysis algorithm to identify a plurality of target points corresponding to the target among the points to obtain the position of the target.

Abstract: A radar system includes transmitters and receivers. The transmitters transmit radio signals. The receivers receive radio signals that include the transmitted radio signals reflected from objects in an environment. Each receiver has a controller, a buffer, and a post-buffer processor. The receiver processes the received radio signals and stored data samples in the buffer. The buffer operates in a plurality of modes defined by the controller. Modes of operation are selected for each of the respective buffers. Each buffer's mode of operation is selected to perform a desired processing on respective data samples. Each of the post-buffer processors receive their respective data samples from the respective buffers and performs further data processing on the respective data samples.

Abstract: This disclosure describes, in part, techniques for displaying location information of an object along with a video depicting the object. For instance, an electronic device may use a radar sensor to generate radar data representing the locations and an imaging device to generate image data representing the video. A user device may then use the image data to display the video. Additionally, the user device may display a map of a geographic area that includes the electronic device over a portion of the video. The electronic device then uses the radar data to determine positions on the map that corresponds to the locations. Using the positions, the electronic device displays interface elements representing the locations of the object. In some circumstances, the interface elements include different characteristics, such as colors, indicating a direction of motion of the object.

Abstract: Exemplary aspects are directed to a radar-based detection circuit or system with signal reception circuitry to receive reflection signals in response to radar signals transmitted towards objects. The system may include logic/computer circuitry and a multi-input multi-output (MIMO) virtual array to enhance resolution or remove ambiguities otherwise present in processed reflection signals. The MIMO array may include sparse linear arrays, each being associated with a unique antenna-element spacing from among a set of unique co-prime antenna-element spacings.
