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.
