A radar system for a vehicle includes: at least one main transmit antenna configured to transmit main radar waves essentially parallel to a road on which the vehicle is standing or driving; at least one main receive antenna configured to receive reflections of the main radar waves off objects on the road; a first street condition monitoring, SCM, transmit antenna configured to transmit first polarized radar waves essentially directed to the road at a first polarization; a second SCM transmit antenna configured to transmit second polarized radar waves essentially directed to the road at a second polarization different from the first polarization; a first SCM receive antenna configured to receive, at the first polarization, reflections of the polarized radar waves off the road; and a second SCM receive antenna configured to receive, at the second polarization, reflections of the polarized radar waves off the road.
