Abstract :
The availability of highly integrated cost-effective 77 GHz SiGe-MMICs creates new possibilities for different applications of radar sensors in the automotive area. The ability to measure angles in azimuth and elevation will be a relevant feature for the upcoming radar generations. We present a beamforming solution for angular measurements in both directions with one single sensor, using a combination of series fed arrays and a cylindrical dielectric lens. With this solution amplitude and phase information are split up and independently used to get the azimuth respectively the elevation angle.
