| 主权项 | 1. An FMCW radar sensor for a motor vehicle, comprising: at least one antenna element having an emission characteristic; a microwave lens having at least one directionality characteristic; and at least one driving circuit having a modulation device, the modulation device variably setting a frequency position of a frequency band to alter a specific variation of the emission characteristic in a direction extending along the directionality characteristic; wherein the antenna element has multiple subelements which are positioned in a vertical column and fed serially. | ||
