Abstract: Methods for disambiguating the location of a radar contact using an N×M dimensioned radar array are provided. In the horizontal plane, the method comprises transmitting a first radar energy pattern in a direction, collecting reflected energy of the first radar energy pattern from the contact, transmitting a second radar energy pattern in the direction and collecting reflected energy of the second radar energy pattern from the contact. The method further comprises comparing the collected energy of the first radar energy pattern and the collected energy of the second radar energy pattern and determining if the contact is located in a side lobe or a main lobe of the first and second radar energy pattern based on the comparison. In the vertical plane, other similar embodiments may be used to determine if the radar antenna(s) are blocked by an obstacle.

Abstract: A flexible, printable antenna for automotive radar. The antenna can be printed onto a thin, flexible substrate, and thus can be bent to conform to a vehicle body surface with compound curvature. The antenna can be mounted to the interior of a body surface such as a bumper fascia, where it cannot be seen but can transmit radar signals afield. The antenna can also be mounted to and blended into the exterior of an inconspicuous body surface, or can be made transparent and mounted to the interior or exterior of a glass surface. The antenna includes an artificial impedance surface which is tailored based on the three-dimensional shape of the surface to which the antenna is mounted and the desired radar wave pattern. The antenna can be used for automotive collision avoidance applications using 22-29 GHz or 76-81 GHz radar, and has a large aperture to support high angular resolution of radar data.
Abstract translation: 用于汽车雷达的灵活可打印天线。 天线可以印刷在薄的柔性基底上，因此可以弯曲以符合具有复合曲率的车身表面。 天线可以安装在诸如保险杠面板之类的身体表面的内部，其中它不能被看到，但是可以在远的地方传输雷达信号。 天线也可以安装到并且混合到不显眼的身体表面的外部，或者可以被制成透明的并且安装到玻璃表面的内部或外部。 天线包括基于安装天线的表面的三维形状和期望的雷达波形图案来裁剪的人造阻抗表面。 该天线可用于使用22-29 GHz或76-81 GHz雷达的汽车防撞应用，并具有大孔径以支持雷达数据的高角度分辨率。
