摘要

毫米波调频连续波(FMCW)雷达有望在不久的将来广泛应用于高级驾驶辅助系统(ADAS)和自动驾驶汽车。由于FMCW雷达使用3-4 GHz带宽来实现10cm级的距离测量分辨率，其密集部署会造成严重的雷达间干扰，导致对目标的未探测和/或误探测。这篇特邀论文概述了汽车FMCW雷达的雷达间干扰，并描述了其缓解挑战，包括我们小组的建议和结果。

Inter-radar interference in automotive FMCW radars and its mitigation challenges

Millimeter-wave FMCW (Frequency Modulated Continuous Wave) radar is expected to be widely used for ADAS (Advanced Driver Assistance System) and automated driving car in near future. As FMCW radar uses 3–4 GHz bandwidth to achieve 10cm class range measurement resolution, its dense deployment can cause serious inter-radar interference resulting in miss-detection and/or false detection of the targets. This invited paper overviews inter-radar interference in automotive FMCW radars and describes its mitigation challenges including the proposals and results of our group.
