A Novel Iterative Inter-Radar Interference Reduction Scheme for Densely Deployed Automotive FMCW Radars

Abstract

Inter-radar interference will be a crucial problem when automotive FMCW radars are densely deployed for advanced driver assistance systems and automated driving cars. This paper proposes a novel iterative inter-radar interference reduction scheme to suppress inter-radar interference from multiple FMCW radars with various received level and chirp rate and shows performance evaluation results by computer simulation to validate the proposed scheme.
