Proposal of Antenna Element Space Interference Cancelling Radar

摘要

This paper focuses on an angle estimation of different-sized targets, which can simulate an angle estimation among tracks, vehicles, bicycles and pedestrians. The problem is that the presence of sidelobe for a large target degrades the accuracy of the angle estimation. In this paper, a novel scheme, called Antenna element space Interference Cancelling (AIC), is proposed for reducing the influence of the sidelobe. Both simulation and experimental results are presented. The angle estimation error using the proposed AIC radar system can be reduced to 2°.
