UWBCarGraz Dataset

Dataset for car occupancy detection using ultra-wideband radar.

The dataset contains radar channel impulse responses (CIRs) in the frequency band from 4.5GHz to 9.5GHz sampled every 0.1s.The CIRs were obtained with participants inside a car performing three different activities (i) breathing, (ii) talking and (iii) moving.

The matlab files are named as "UWBCarGraz_<fc>_<bw>_<activity>.mat" were fc is the center frequency and bw the bandwidth of the used pulse and activity the activity the participants performed inside the car. Each .mat file contains a NxMxP matrix of CIRs where the first dimension corresponds to fast time, the second dimension corresponds to slow time and the last dimension corresponds to different samples in the dataset.

For more information about the data see [1] and the PDF document contained in the dataset.

基于超宽带雷达（Ultra-wideband Radar）的车内乘员检测数据集。
本数据集包含频段范围为4.5GHz至9.5GHz的雷达信道冲激响应（Channel Impulse Responses, CIRs），采样间隔为0.1秒。该雷达信道冲激响应的采集场景为车内受试者开展三种不同活动：(i) 呼吸、(ii) 交谈以及(iii) 肢体移动。

MATLAB文件命名格式为"UWBCarGraz_<fc>_<bw>_<activity>.mat"，其中fc代表所用脉冲的中心频率，bw代表脉冲带宽，activity则对应受试者在车内开展的活动类型。每个.mat文件均包含一个N×M×P维度的雷达信道冲激响应矩阵：第一维度对应快时间，第二维度对应慢时间，第三维度则对应数据集中的不同采样样本。
