超宽带雷达人体动作四维成像数据集

数据主编：金添 超宽带雷达人体动作四维成像数据集（UWB-HA4D）1.0，发布2757组超宽带MIMO雷达人体动作四维成像数据。该数据集通过超宽带MIMO雷达系统进行探测、成像获得，雷达工作频段为1.78-2.78 GHz，信号体制为步进频信号，系统采用10发10收的二维MIMO阵列排布。 该数据集共采集了11个人体目标的动作数据，动作类型有站立、坐下、挥手、打拳、走路、踢腿等10种常见动作，数据采集场景有3种，分别是：不遮挡的自由空间场景、3cm厚塑料板遮挡场景、27cm厚砖墙遮挡场景。本数据集设置自由空间场景的9人的动作数据为训练集，其他2人的动作数据为测试集；设置2个遮挡场景的人体动作数据为测试集。详细的数据标注信息见论文。 本数据集中的雷达数据维度为40×64×64×64，其中64×64×64是三维雷达图像的大小，40是三维雷达图像的帧数，数据格式为mat。 图1 数据集构建流程 数据使用详见论文 “UWB-HA4D-1.0: 超宽带雷达人体动作四维成像数据集” 和“UWB-HA4D-1.0-超宽带雷达人体动作四维成像数据集使用说明”。

Dataset Editor-in-Chief: Jin Tian. Ultra-wideband Radar Human Motion 4D Imaging Dataset (UWB-HA4D) 1.0: A total of 2757 sets of ultra-wideband MIMO radar human motion 4D imaging data are released.

This dataset is acquired through detection and imaging using an ultra-wideband MIMO radar system. The radar operates in the frequency band of 1.78–2.78 GHz, employs stepped-frequency signals as its transmission scheme, and is configured with a 2-dimensional MIMO array layout with 10 transmitters and 10 receivers.

Motion data from 11 human subjects are collected in this dataset, covering 10 common motion types including standing, sitting, waving, punching, walking, kicking, and so on. Three data collection scenarios are designed: unobstructed free space scenario, 3 cm-thick plastic board-obstructed scenario, and 27 cm-thick brick wall-obstructed scenario.

For this dataset, the motion data of 9 subjects in the free space scenario are designated as the training set, while the motion data of the remaining 2 subjects serve as the test set; the human motion data collected in the two obstructed scenarios are also categorized as the test set. Detailed data annotation information can be found in the accompanying paper.

The radar data in this dataset has a dimension of 40×64×64×64, where 64×64×64 represents the size of a single 3D radar image, 40 is the number of frames of such 3D images, and the data is stored in .mat format.
