The present invention relates to a radar system (1) configured to be installed at a vehicle, the radar system comprising: a processing device (6, 7) having a plurality of transmit outputs and a plurality of receive inputs; at least one main transmit antenna (TX11, TX12, TX21, TX22) being configured to transmit main radar waves essentially parallel to a road on which the vehicle is standing or driving, and being communicatively coupled to the processing device via a first transmit output; at least one main receive antenna (RX11, RX12, RX13, RX21, RX22, RX23) being configured to receive reflections of the main radar waves off objects on the road, and being communicatively coupled to the processing device via a first receive input; a first street condition monitoring, SCM, transmit antenna (2) being configured to transmit first polarized radar waves essentially directed to the road at a first polarization, and being communicatively coupled to the processing device via a second transmit output; a second SCM transmit antenna (5) being configured to transmit second polarized radar waves essentially directed to the road at a second polarization different from the first polarization, and being communicatively coupled to the processing device via a third transmit output; and a first SCM receive antenna (4) being configured to receive, at the first polarization, reflections of the polarized radar waves off the road, and being communicatively coupled to the processing device via a second receive input; and a second SCM receive antenna (3) being configured to receive, at the second polarization, reflections of the polarized radar waves off the road, and being communicatively coupled to the processing device via a third receive input.
