I+ Lab RadSet v1

现有的公开数据集往往存在数据量小，训练过程不充分，导致过拟合严重，泛化性能差的问题。针对这一问题，构建了雷达数据集 RadSet。在数据获取阶段，frequency modulated continuous wave (FMCW) radar system IWR1843 Boost manufactured by Texas Instruments (TI) was used. The RadSet dataset is collected by I+ Lab at Shandong University, covering a rectangular area 5 meters long in front of the radar and 4 meters wide, with the radar placed at a height of 120 cm above the ground. The volunteers execute the aforementioned activities at distances ranging between 1 to 5 meters from the radar. The RadSet captures six types of daily activities, including 1) bending; 2) fall; 3) jumping; 4) punching; 5) jogging; and 6) walking, performed by 10 volunteers. Bending refers to lowering the body to pick up an object from the ground while remaining in the same position. Fall describes a sudden loss of balance, resulting in a fall during walking or standing. Jumping involves propelling the body off the ground in place. Punching refers to throwing a punch within the entire radar field of view. Jogging refers to running at a moderate speed without a fixed direction. Walking refers to moving at a steady pace without a specific direction.
