Abstract
This paper focuses on the effect of range velocity displacement of two targets on the accuracy of direction-of-arrival estimation in an automotive radar system. A simulative analysis is performed to evaluate the effect on the received signal phases for two targets with different positions, i.e. range and velocity displacement, within a range velocity cell. Experiments show an increasing error of the maximum likelihood estimation for two targets azimuth angle, as their spacing within the range velocity cell is increased. Finally the root cause and the impact of this behavior on real-world scenarios is analyzed.
