摘要

本文给出了适用于高距离分辨率雷达的广义微多普勒分析结果。在这里,目标回波能量以时间、多普勒和距离的三维空间表示,这比在时间多普勒平面上进行的标准微多普勒分析可以提供更多的目标微运动信息。分析信号用1GHz高带宽的ka波段FMCW雷达记录,在距离、时间和速度上具有较好的分辨率。在此,我们提出了一种在地面干扰背景下观察跑步者微距离和微多普勒效应的新方法。

Micro-range, micro-Doppler joint analysis of pedestrian radar echo
We present in the paper results of a generalised micro-Doppler analysis that is suited to high range resolution radar. The target echo energy is here represented in the three dimensional space of time, Doppler, and additionally range, what can provide more information on target micro-motion than the standard micro-Doppler analysis which is performed in the time-Doppler plane. The analyzed signals were recorded with a Ka-band FMCW radar of a high 1GHz bandwidth, which could provide good resolution in range, time and velocity. Here, we present a new method to visualize jointly micro-range and micro-doppler effects of a running man observed on the background of ground interferences.
