摘要

这项工作提出了一项关于生物雷达设备用于实验室动物呼吸节律非接触监测的可行性研究。实验在实验室条件下对睡眠大鼠进行,使用两台SFCW雷达,工作频率范围为3.6-4.0 GHz和13.8-14.2 GHz。每个雷达监测大鼠的呼吸模式和运动活动。实验结果分析表明,使用更高的探测频率更可取,并且可以可靠地估计实验动物在睡眠中的呼吸模式。

Comparison of 4 GHz and 14 GHz SFCW radars in measuring of small laboratory animals vital signs
The work presents a feasibility study on the possible bioradar devices usage for contactless monitoring of the laboratory animals respiratory rhythm. Experiments are performed in laboratory conditions on sleeping rats by using two SFCW radars operating at frequency ranges of 3.6-4.0 GHz and 13.8-14.2 GHz. Respiration pattern and movement activity of a rat were monitored by each radar. Experimental results analysis revealed that usage of higher probing frequencies is more preferable and allows reliable estimation of respiratory pattern of laboratory animals in sleep.
