    摘要： Examples disclosed herein relate to a radar system for object identification. The radar system transmitting an azimuth fan beam and incrementing elevation of the beam. The radar system may include a transmit antenna and a receive antenna, each having a plurality of antenna elements arranged in rows and columns. The radar system may include a transceiver coupled to the transmit antenna and the receive antenna, the transceiver configured to control transmit beams having an azimuth fan beam, or an elevation fan beam. The radar system may include a processing unit. In various embodiments, the processing unit may include a digital processing unit; a range Doppler mapping module; and an azimuth detection module coupled to the transceiver. The azimuth detection module may be configured to process received signals and identify an azimuth angle of arrival by correlating signals received at antenna elements in rows of the receive antenna.

    摘要： A reflectarray for an antenna system for use in wireless communications is described. The reflectarray includes a substrate and a plurality of cells configured in an array on the substrate. Each cell in the plurality of cells includes three dipoles arranged in a parallel configuration with a length of a center dipole is longer than a length of a lateral dipole. The length of the lateral dipole is 65% of the length of the center dipole. The plurality of cells can include a first set of three parallel dipoles arranged in a first direction and a second set of three parallel dipoles in a second direction that is orthogonal to the first direction. The first set of three parallel dipoles and the second set of three parallel dipoles are shifted half a period along both the first direction and the second direction in the array.

    摘要： In accordance with various embodiments, a multi-layer electromagnetic device is provided. The device includes a first connectivity layer that includes a first conductive pad having a first capacitance, a feed line coupled between the first conductive pad and a transmit signal source, and a first antipad surrounding at least a portion of the first conductive pad that enables an isolation of electromagnetic signals propagating through the first conductive pad. The first antipad has a resonance that is a function of the first capacitance. The device also includes a second connectivity layer that includes a second conductive pad that enables an electrical connectivity to an external device and a plurality of layers positioned between the first connectivity layer and the second connectivity layer. The conductive pads have antipad extensions into available area of the layer as a function of a capacitance of the conductive pads.

    摘要： Examples disclosed herein relate to an autonomous driving system in an ego vehicle. The autonomous driving system includes a radar system configured to detect and identify a target in a path and a surrounding environment of the ego vehicle. The autonomous driving system also includes a sensor fusion module configured to receive radar data on the identified target from the radar system and compare the identified target with one or more targets identified by a plurality of perception sensors that are geographically disparate from the radar system. Other examples disclosed herein include a method of operating the radar system in the autonomous driving system of the ego vehicle.

    摘要： Examples disclosed herein relate to a beam steering radar for use in an autonomous vehicle. The beam steering radar has a radar module with at least one beam steering antenna, a transceiver, and a controller that can cause the transceiver to perform, using the at least one beam steering antenna, a first scan of a first field-of-view (FoV) with a first chirp slope in a first radio frequency (RF) signal and a second scan of a second FoV with a second chirp slope in a second RF signal. The radar module also has a perception module having a machine learning-trained classifier that can detect objects in a path and surrounding environment of the autonomous vehicle based on the first chirp slope in the first RF signal and classify the objects based on the second chirp slope in the second RF signal.
