Doppler Beam Sharpening for High-Resolution Imaging in Dynamic Automotive Scenes

With the current push towards increased levels of autonomy in the automotive sector, accurate sensing of the vehicle surroundings is critical, even under challenging environmental conditions. Automotive radar is well suited to this application. This paper describes a novel approach which uses a combination of Doppler beam sharpening, for high resolution imaging of the stationary environment, and a multi-target tracker for estimating the positions and velocities of dynamic targets. Experimental results recorded from a moving vehicle are presented.
