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

The file "target_CIR.mat" 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.mat"包含了多静态超宽带（Ultra Wide Band，UWB）系统（含7个模块）在住宅环境中，当目标执行行走、坐立、站立等各类活动（包括无活动时段）时采集到的信道冲激响应（Channel Impulse Response，CIR）数据。该数据集文件主要包含复信道冲激响应数据（单次测量含50个采样点）、毫秒级精度时间戳、收发节点详细信息、活动标签、目标的基准真值XY坐标，以及Qorvo公司DW1000芯片组上报的各类实用超宽带参数，例如信道冲激响应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、信道冲激响应功率值、前导码累加计数值、噪声最大值与噪声标准差等。
