Abstract :
With the rapid development of highly integrated 77 GHz SiGe-Radar-MMICs, cost effective and reliable radar systems are feasible to significantly increase driving safety in all vehicle classes. New functions have to be implemented in these sensors to fulfill the demanding requirements in future advanced driver assistance systems. One criterion will be the exact measurement of angles in the azimuth and also in the elevation plane. A beamforming concept for angular measurements in both directions with one single sensor, using a combination of series fed arrays and a cylindrical dielectric lens, is presented in this paper.
