Abstract: Example embodiments relate to corrugated radomes for protecting and concealing components of radar units. An example radar system may include a radar unit that includes at least one antenna having a radiation pattern. The radar unit is configured to transmit a radar signal based on the radiation pattern and receive radar signals. In addition, the radar system further includes a radome located in a direction of transmission of the radiation pattern. Particularly, the radome includes a stepped surface having at least one step that includes a height equal to one-quarter of a wavelength at a frequency of operation of the radar unit. The least one step is positioned on the radome such that the at least one step causes deconstructive interference of reflections of the transmitted radar signal caused by the radome.

Abstract: The technology employs a contrasting color scheme on different surfaces for sensor housing assemblies mounted on exterior parts of a vehicle that is configured to operate in an autonomous driving mode. Lighter and darker colors may be chosen on different surfaces according to a thermal budget for a given sensor housing assembly, due to the different types of sensors arranged along particular surfaces, or to provide color contrast for different regions of the assembly. For instance, differing colors such as black/white or blue/white, and different finishes such as matte or glossy, may be selected to enhance certain attributes or to minimize issues associated with a sensor housing assembly.

Abstract: An apparatus includes a first waveguide configured to propagate electromagnetic energy along a propagation direction. The apparatus further includes a first waveguide flange configured to selectively operate in one of a plurality of modes. When operating in a first mode, the apparatus radiates at least a portion of the electromagnetic energy from the first waveguide via at least one radiating feature of the first waveguide flange. The at least one radiating feature is located on a surface of the first waveguide flange that is perpendicular to the propagation direction. Additionally, when operating in a second mode, the apparatus conducts at least a portion of the electromagnetic energy from the first waveguide to a subsequent element (e.g., a second waveguide). The at least one radiating feature is shorted to a portion of the subsequent element when operating in the second mode.
