Abstract

In a lens arrangement for collimating radar waves for distance sensors, in particular for motor vehicles, several sublenses are arranged integrally next to one another. A lobe enlargement necessary for angular analysis is thereby achieved. The range is only slightly reduced as compared to a lens having a surface area of the same size.
