要約(日本語): This paper focuses on an angle estimation of_x000D_ different-sized targets, which can simulate an angle estimation_x000D_ among tracks, vehicles, bicycles and pedestrians. The problem_x000D_ is that the presence of sidelobe for a large target degrades the_x000D_ accuracy of the angle estimation. In this paper, a novel scheme,_x000D_ called Antenna element space Interference Cancelling (AIC),_x000D_ is proposed for reducing the influence of the sidelobe. Both_x000D_ simulation and experimental results are presented. The angle_x000D_ estimation error using the proposed AIC radar system can be_x000D_ reduced to 2 degree.
