Abstract

A front end of a radar system is provided with a first front end apparatus and a second front end apparatus. A first transmit planar component and a first receive planar component in the first front end apparatus are arranged to be perpendicular to one another. A second transmit planar component and a second receive planar component in the second front end apparatus are arranged to be perpendicular to one another. A linear array of antennas is located along a second end of each planar component. Polarization of a first set of waves transmitted from the linear array of antennas of the first transmit planar component and polarization of a second set of waves transmitted from the linear array of antennas of the second transmit planar component are perpendicular to one another.
