Target Channel Impulse Response (CIR) data (in .csv format)

The file "target_CIR.csv" contains the CIR data recorded from the multi-static UWB system (7 modules) in the residential environment when the target was performing various activities such as walking, sitting, and standing (including the no activity portions). The dataset files basically consist of complex CIR data (50 samples per measurement), timestamps with millisecond precision, details about the transmitting and receiving nodes, activity labels, ground truth XY coordinates of the target, as well as some other useful UWB parameters that are reported by the Qorvo’s DW1000 chipset, for example, detected first path index and first path amplitudes of CIR measurements, first path and received power levels, CIR power value, preamble accumulation count value, maximum value of noise, standard deviation of noise, etc.文件"target_CIR.csv"中存储了由7个模块组成的多静态超宽带（Ultra Wide Band，简称UWB）系统，在住宅环境中当测试目标执行行走、落座、站立等各类活动（包含无活动静止时段）时所记录的信道冲激响应（Channel Impulse Response，简称CIR）数据。该数据集文件主要包含复数值CIR数据（单次测量含50个采样点）、毫秒级精度的时间戳、收发节点详细信息、活动标签、目标的地面真值XY坐标，以及Qorvo公司DW1000芯片组上报的其他若干实用UWB参数，例如CIR测量的检测首径索引与首径幅度、首径功率与接收功率电平、CIR功率值、前导码累加计数值、噪声最大值、噪声标准差等。
