Example embodiments relate to slanted radomes for protecting 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 is aligned at an angle relative to a plane of the at least one antenna such that reflections of the transmitted radar signal caused by the radome are directed towards at least one of a null of the radiation pattern and an absorption component.
