摘要

随着自动驾驶技术的进步，汽车雷达系统的市场渗透率和功能重要性不断提高。汽车雷达之间的多址干扰(串扰)将更加频繁地发生，从而降低了雷达的探测能力。对于即将到来的新要求，例如用雷达探测道路上的小型静态目标，其后果尤其重要。本文研究了前置数字波束形成(DBF)雷达由于相邻轨道上存在非相干干扰而导致的性能下降。介绍了一种估计串扰信噪比损失的模型，重点讨论了干扰周期和干扰量对啁啾序列雷达的影响。此外，还考虑了数字波束形成的影响。对干扰源的相对位置进行了最坏情况分析。

Estimation of the Influence of Incoherent Interference on the Detection of Small Obstacles with a DBF Radar

As the technology of automated driving progresses, the market penetration and the functional importance of automotive radar systems are on the rise. Multiple access interference (crosstalk) between automotive radars will occur more often, reducing the detection capabilities of radars. The consequences are particularly critical regarding upcoming new requirements, such as the detection of small static targets in the road by radar. This Paper investigates the performance reduction of front mounted digital beamforming (DBF) radars due to the presence of an incoherent interferer on the neighboring track. A model for the estimation of signal-to-noise-ratio-loss due to crosstalk is introduced, focusing the impact of interference periods and quantities on chirp sequence radars. Further, the influence of digital beamforming is taken into account. A worst-case analysis regarding the relative position of the interferer is performed.
