Abstract: A vehicle, driving system and method for driving a vehicle is disclosed. The driving system includes a radar system, a processor and an autonomous driving system. The radar system obtains an SAR measurement of a static object in an environment of the vehicle. The processor obtains a first estimate of a location of the vehicle in the environment, obtains from a database a representation of a static object in the environment associated with the first estimate of the location, and compares the SAR measurement of the static object to the representation of the static object from the database to obtain a second estimate of the location of the vehicle. The autonomous driving system drives the vehicle through the environment based on the second estimate of the location of the vehicle.

Abstract: Methods and systems are provided for controlling a radar system of a vehicle. In particular a method is taught for updating a radar detection threshold according to a cluster power and cluster tracking information. The method then updates the detector for that specific known region wherein each cluster may have its own unique threshold.

Abstract: A method and apparatus for calibrating a LiDAR system at a first location with a radar system at a second location. A calibration target is placed at a location and orientation with respect to the LiDAR system and the radar system. Coefficients of a plane of the calibration target are determined in a frame of reference of the LiDAR system. Coordinates of the calibration target are determined in a frame of reference of the radar system. A cost function is composed from a planar equation that includes the determined coefficients and the determined coordinates and a relative pose matrix that transforms the frame of reference of the radar system to the frame of reference of the LiDAR system. The cost function is reduced to estimate the relative pose matrix for calibration of the LiDAR system with the radar system.

Abstract: A system and method to achieve angular ambiguity resolution in a two-dimensional Doppler synthetic aperture radar system include transmitting pulses using a plurality of transmit elements during movement of a platform on which the system is mounted. Reflections are received from a target resulting from the pulses and the reflections are processed to determine a Doppler measurement. The processing includes isolating movement of the target in the Doppler measurement, and determining a target azimuth angle and a target elevation angle to the target based on an iterative process that includes estimating the target elevation angle or the target azimuth angle and then determining the target azimuth angle or the target elevation angle, respectively, based on a beamforming matrix. The beamforming matrix indicates amplitude and phase at each azimuth angle and each elevation angle among a set of azimuth angles and a set of elevation angles.
