数据主编：韦顺军 高分辨三维毫米波雷达数据集(3DRIED)1.0，发布81组毫米波雷达三维成像回波数据及影像。该数据集获取模式为毫米波传感器沿二维平面扫描进行近场成像，扫描尺寸大小为0.4m×0.4m，雷达中心频率为78.8GHz，发射信号带宽为3.6GHz。毫米波传感器在距离向、水平向和垂直向的信号采样点数分别为256点、407点和200点，形成的单通道原始回波数据维度为256×407×200。 近场观测目标包括了刀具、枪械等金属目标，涵盖了单个目标、多个目标以及隐匿目标（纸盒、布袋）等环境条件。 本数据集中雷达传感器具有4个接收通道，最终数据集中原始回波数据维度为256×407×200×4。回波数据格式为mat（Matlab软件矩阵文件），同时提供了观测目标场景光学图像、二维与三维成像的参考影像。 图 数据集构建及目标示例 数据使用详见 “高分辨三维毫米波雷达数据集使用说明” 和“Matlab成像预处理代码”。

Data Editor: Wei Shunjun. High-Resolution 3D Millimeter-Wave Radar Dataset (3DRIED) 1.0: A total of 81 sets of millimeter-wave radar 3D imaging echo data and images are released. The dataset is acquired via near-field imaging by scanning the millimeter-wave sensor along a two-dimensional plane, with a scanning size of 0.4 m × 0.4 m, a radar center frequency of 78.8 GHz, and a transmitted signal bandwidth of 3.6 GHz. The signal sampling counts of the millimeter-wave sensor in the range, azimuth and elevation directions are 256, 407 and 200 respectively, resulting in a single-channel raw echo data dimension of 256 × 407 × 200. Near-field observation targets include metallic objects such as knives and firearms, covering scenarios with single targets, multiple targets, and concealed targets (paper boxes, cloth bags). The radar sensor in this dataset is equipped with 4 receive channels, so the final dimension of the raw echo data in the dataset is 256 × 407 × 200 × 4. The echo data is stored in MAT format (Matlab matrix files), and optical images of the observed target scenes as well as reference images for 2D and 3D imaging are also provided.
