摘要翻译：
雷达传感器可以用来分析由微运动引起的频率漂移，在距离维和速度维上分别被识别为微多普勒($\boldsymbol{\mu}-d)和微距离($\boldsymbol{\mu}-r)。不同的移动目标将具有唯一的$\boldsymbol{\mu}$-d和$\boldsymbol{\mu}$-r签名，可用于目标分类。这种分类方法可以应用于许多领域，如步态识别、安全和监控等。本文将25 GHz FMCW单输入单输出(SISO)雷达应用于工业安全领域，实现了实时的人机识别。由于实时性的限制，我们直接对联合距离-多普勒（R-D）图进行分析。在此基础上，对传统的手工提取特征的经典学习方法、集成分类器和深度学习方法进行了比较。对于集成分类器，重构的距离和速度剖面直接传递给集成树，如梯度增强和随机森林，而不进行特征提取。最后，使用深度卷积神经网络(DCNN)，将原始R-D图像直接输入到所构造的网络中。DCNN在单个R-D地图上识别人类和机器人的准确率高达99%。

英文摘要：
Radar sensors can be used for analyzing the induced frequency shifts due to micro-motions in both range and velocity dimensions identified as micro-Doppler ($\boldsymbol{\mu}$-D) and micro-Range ($\boldsymbol{\mu}$-R), respectively. Different moving targets will have unique $\boldsymbol{\mu}$-D and $\boldsymbol{\mu}$-R signatures that can be used for target classification. Such classification can be used in numerous fields, such as gait recognition, safety and surveillance. In this paper, a 25 GHz FMCW Single-Input Single-Output (SISO) radar is used in industrial safety for real-time human-robot identification. Due to the real-time constraint, joint Range-Doppler (R-D) maps are directly analyzed for our classification problem. Furthermore, a comparison between the conventional classical learning approaches with handcrafted extracted features, ensemble classifiers and deep learning approaches is presented. For ensemble classifiers, restructured range and velocity profiles are passed directly to ensemble trees, such as gradient boosting and random forest without feature extraction. Finally, a Deep Convolutional Neural Network (DCNN) is used and raw R-D images are directly fed into the constructed network. DCNN shows a superior performance of 99\% accuracy in identifying humans from robots on a single R-D map.
