Radar device for behind windshield installations

摘要

A ground vehicle radar system (10) includes a windshield (14) of the ground (26) vehicle (16) and a radar device (12) installed behind the windshield (14). The windshield (14) includes a metallization layer configured to inhibit propagation of infrared radiation (28) through the windshield (14) 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 (12) to pass through. An antenna of the radar device (12) is installed behind the windshield (14) and aligned with the opening. A lower portion of the antenna has a first field of view (18) through the opening characterized as being directed horizontal toward a horizon (20) forward of the vehicle (16). An upper portion of the antenna has a second field of view (18) through the opening characterized as being directed downward toward an area (24) of the ground (26) forward of the vehicle (16).
