摘要

近年来,基于连续波雷达的协同调频测距定位系统受到了广泛的关注。在本文中,我们提出了一种新的分析这些非相干系统性能的方法,特别关注相位噪声的影响。我们展示了在不同信噪比条件下的行为,并比较了两种相互竞争的评估概念。在5.8 GHz ISM频段的原型测距系统上进行了实测数据验证。

Performance analysis of cooperative FMCW radar distance measurement systems
In recent years, cooperative frequency-modulated continuous-wave radar based ranging and positioning systems attained significant attraction. In this paper, we present a novel analysis approach of the performance of these incoherent systems, with a special focus set on phase noise effects. We show the behavior in different signal to noise ratio conditions and compare two competing evaluation concepts. The results are verified on real measurement data, taken with a prototype ranging system in the 5.8 GHz ISM band.
