Abstract
Radar-based environment mapping is considered as one of the key technology for highly automated driving. This paper presents an efficient radar map generation based on newly proposed Doppler coherent focusing Direction-Of-Arrival (DOA) method. This method consists of Doppler coherent Angle-Of-Interest (AOI) prediction and DOA steering vector adaptation. The simulation shows that the proposed DOA methods outperformed the conventional approach in both computational cost and radar grid map resolution. In addition, real data obtained from a 77GHz radar sensor are presented to show the effectiveness of the proposed approach practically.
