    Abstract: A method for using Synthetic Aperture Radar (SAR) to perform a maneuver in a land vehicle is provided. The method includes: receiving digitized radar return data from a radar transmission from a SAR onboard the vehicle; accumulating a plurality of frames of the digitized radar return data; applying a RADON transform to the accumulated plurality of frames of the digitized radar return data and odometry data from the vehicle to generate transformed frames of data for each three-dimensional point, wherein the RADON transform is configured to perform coherent integration for each three-dimensional point, project a radar trajectory onto each three-dimensional point, and project Doppler information onto each three-dimensional point; generating a two-dimensional map of an area covered by the radar transmission from the SAR based on the transformed frames of data for each three-dimensional point; and performing a maneuver with the land vehicle by applying the generated two-dimensional map.

    Abstract: A hyperbolic waveform multiple-input multiple-output radar includes a generator circuit, multiple transmit circuits, a multiple-input multiple-output antenna, and multiple receive circuits. The generator circuit may be operable to generate a linear frequency modulated signal and a hyperbolic frequency modulated signal. The transmit circuits may be operable to generate multiple transmit signals by analog mixing the linear frequency modulated signal and the hyperbolic frequency modulated signal in response to a plurality of coding family parameters, wherein the transmit signals define an orthogonal family of waveforms. The multiple-input multiple-output antenna may be operable to transmit the transmit signals toward an object and receive multiple receive signals from the object. The receive circuits may be operable to determine multiple data signals in response to the receive signals, wherein the data signals are suitable to determine a distance between the multiple-input multiple-output antenna and the object.

    Abstract: A system and method to generate a family of orthogonal signals for a code division multiple access (CDMA) radar system involve selecting a first signal of the family of orthogonal signals for transmission by one of a plurality of transmitters of the radar system. The method includes using an algorithm to determine a second signal of the family of orthogonal signals. The algorithm uses cross-correlation values between candidate signals for consideration as the second signal of the family of orthogonal signals and the first signal. The method also includes transmitting the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals simultaneously from two different transmitters, and obtaining and processing reflections resulting from transmission of the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals.

    Abstract: A system and method to use deep learning for super resolution in a radar system include obtaining first-resolution time samples from reflections based on transmissions by a first-resolution radar system of multiple frequency-modulated signals. The first-resolution radar system includes multiple transmit elements and multiple receive elements. The method also includes reducing resolution of the first-resolution time samples to obtain second-resolution time samples, implementing a matched filter on the first-resolution time samples to obtain a first-resolution data cube and on the second-resolution time samples to obtain a second-resolution data cube, processing the second-resolution data cube with a neural network to obtain a third-resolution data cube, and training the neural network based on a first loss obtained by comparing the first-resolution data cube with the third-resolution data cube. The neural network is used with a second-resolution radar system to detect one or more objects.

    Abstract: A method of mitigating vibration in a radar system on a moving platform includes obtaining received signals resulting from reflections of transmitted signals by one or more objects in a field of view of the radar system. The received signals are a three-dimensional data cube. The method also includes processing the received signals to obtain a first three-dimensional map and second three-dimensional map, estimating the vibration based on performing a first detection using the second three-dimensional map, and cancelling the vibration from the first three-dimensional map to obtain a corrected first three-dimensional map. A corrected second three-dimensional map is obtained by further processing the corrected first three-dimensional map; and a second detection is performed using the corrected second three-dimensional map.

    Abstract: System and method of controlling operation of an optical sensor in a device. The optical sensor is configured to employ a scan pattern to scan respective portions of a full field of view. A navigation sensor is configured to obtain location coordinates of the device. An inertial sensor is configured to obtain an acceleration data of the device in a plurality of directions. A controller is configured to determine a position of the device at the present time based in part on the location coordinates and the acceleration data. The controller is configured to determine a sun striking zone based in part on a relative position of the sun and the device. When a sun overlap region between the respective portions of the full field of view and sun striking zone exceeds a first overlap threshold, operation of the optical sensor is modified.
