A ground vehicle radar system includes a windshield of the ground vehicle and a radar device installed behind the windshield. The windshield includes a metallization layer configured to inhibit propagation of infrared radiation through the windshield that also inhibits the propagation of radar signals. The metallization layer defines an opening in the metallization layer for radar signals emitted and detected by a radar device to pass through. An antenna of the radar device is installed behind the windshield and aligned with the opening. A lower portion of the antenna has a first field of view through the opening characterized as being directed horizontal toward a horizon forward of the vehicle. An upper portion of the antenna has a second field of view through the opening characterized as being directed downward toward an area of the ground forward of the vehicle.
