Inter-Radar Interference Analysis and Concept of Scalable Fast Chirp FMCW Radar for Automotive Applications

Inter-radar interference of automotive FMCW radars can be a serious problem for their dense deployment in near future. This paper describes inter-radar interference analysis of fast chirp FMCW radar and proposes a concept of scalable fast chirp FMCW radar for automotive applications. Evaluation results validate the proposed concept can improve the performance degradation of fast chirp FMCW radar while meeting various design requirements.
