Medical radar signal dataset

Data information Subjects : 9 subjects (5 males, 4 females, mean age 24±5 years) Data format : raw signals (.lvm & .csv files.) File structure : The first 22 lines comprised a header. The variable names were displayed on line 23 in each column. After line 24, the signals were displayed. The information stored in each column was as follows: column 1: time; column 2: 24 GHz radar I-channel; column 3: 24 GHz radar Q-channel; column 4: 10 GHz radar I-channel; column 5: respiratory band signal; and column 6: ECG signal. Sampling rate : 1000 Hz Measurement time : 10 min Also refer to the MATLAB code that pre-processes the signals and calculates the respiration rate and heart rates.

数据信息 受试对象：共9名受试者，其中男性5名、女性4名，平均年龄24±5岁。数据格式：原始信号（.lvm与.csv文件）。文件结构：前22行为文件头，第23行以列形式标注各变量名称，第24行及之后为信号数据。各列存储信息如下：第1列为时间；第2列为24 GHz雷达同相（I）通道数据；第3列为24 GHz雷达正交（Q）通道数据；第4列为10 GHz雷达同相（I）通道数据；第5列为呼吸带信号；第6列为心电图（ECG）信号。采样率：1000 Hz。采集时长：10分钟。另可参考用于预处理信号并计算呼吸频率与心率的MATLAB代码。
