Abstract: A radar system includes a split-block assembly unit comprising a first portion and second portion, where the first portion and the second portion form a seam. The radar system further includes a plurality of ports located on a bottom side of the second portion opposite the seam. Additionally, the radar system includes a plurality of radiating elements located on a top side of the first portion opposite the seam. The plurality of radiating elements is arranged in a plurality of arrays. The plurality of arrays includes a set of multiple-input multiple-output (MIMO) transmission arrays, a set of synthetic aperture radar (SAR) transmission arrays, and at least one reception array. Further, the radar system includes a set of waveguides configured to couple each array to a port.

Abstract: The radar system include a plurality of radiating elements arranged in a linear array configured to radiate electromagnetic energy. The radar system also includes a waveguide configured to guide electromagnetic energy between (i) each of the plurality of radiating elements and (ii) a waveguide feed. The radiating elements are coupled to a first side of the waveguide. The radar system additionally includes a waveguide feed configured to couple the electromagnetic energy between the waveguide and a component external to the waveguide. The waveguide feed is coupled to the second side of the waveguide at a position between two of the radiating elements. Further, the radar system includes a power dividing network defined by the waveguide and configured to divide the electromagnetic energy injected by the waveguide feed based on a taper profile.

Abstract: Example systems and methods are disclosed for determining vehicle pose data for an autonomous vehicle. The vehicle computer system may receive pose data from multiple pose measurement systems of the autonomous vehicle. Each pose measurement system may include one or more corresponding sensors of the autonomous vehicle. The vehicle computer system may determine a pose data quality for the received pose data for each pose measurement system. The vehicle computer system may set the vehicle pose data to the pose data of the pose measurement system with the highest pose data quality. The vehicle computer system may control the autonomous vehicle based on the vehicle pose data.
