1. A radar system comprising:
a radar unit that includes a plurality of antennas having a radiation pattern, wherein the plurality of antennas are arranged in a linear array, and wherein the radar unit is configured to: (i) transmit a radar signal based on the radiation pattern, and (ii) receive radar signals; and
a radome located in a direction of transmission of the radiation pattern, wherein the radome includes a stepped surface having at least one step, wherein the at least one step has a height chosen such that the at least one step causes deconstructive interference of reflections of the transmitted radar signal caused by the radome.
