Thoracic echo signal data based on FMCW radar

The data utilized the IWR1642 FMCW radar and the DCA1000EVM data acquisition board from Texas Instruments. Three different environments—bedroom, shared office, and unoccupied conference room—were selected as potential scenarios for non-contact vital sign monitoring. Continuous monitoring was conducted at distances of 0.5, 1, 1.5, and 2m for 120s. The results were calculated using a 30-second data window, with 91 calculations performed during each monitoring session, starting from the 30th second and continuing until the 120th second.

本数据集采用了德州仪器公司生产的IWR1642 FMCW雷达和DCA1000EVM数据采集板。选取卧室、共享办公室以及空置的会议室三个不同环境作为非接触式生命体征监测的潜在场景。在距离0.5米、1米、1.5米和2米处，持续监测了120秒。结果计算采用30秒数据窗口，每个监测过程中进行91次计算，自第30秒开始，持续至第120秒结束。
