傳統監護心跳率與呼吸率皆需使用接觸式方式進行量測，其線路連接 與電極黏貼將造成受測者之不便與皮膚不適，因此本論文將以開發非接觸 式量測心跳率與呼吸率監護系統為主軸，提供受測者更加舒適的環境，而在 本論文將以UWB 雷達進行開發非接觸式心跳率與呼吸率監護介面。 先前的研究顯示UWB 雷達系統可被使用於遠程生命象徵監護，且主要 應用於救災和健康監護。在本篇論文中所使用之UWB 雷達回波訊號包含多 個深度資訊，因此開發自動目標深度收尋機制，再對該深度UWB 雷達回波 進行分析人體訊號，並開發偵測胸腔移動以計算心跳與呼吸個數機制。 最後透過量測不同受測者驗證本論文所提之機制，其實驗結果顯示心 跳次數及呼吸次數正確率皆可達95%以上。;Traditionally, heart rate and respiratory measurement require contacting directly to skin, which will let the patient feel uncomfortable and inconvenient due to the attachment of electrode and the wires. Therefore, this paper develops a contactless measurement of heart rate and respiratory rate monitoring system, which provides the user a comfortable way for measuring the heartbeat and breathing signal. The interface of the system is developed based on the UWB radar. Previous studies have shown that the UWB radar and be used for remote vitalsigns monitoring, mainly applied in health monitoring and rescue scenarios. The UWB radar echo signal used in this paper contains many depths information. In order to find the depth of the target, this paper develops an automatic method. After having the target depth, we analyze the physiology signal from the echo signal to develop a method for calculating the heartbeat and breathing number by measuring the displacement of chest. The method is verified by the experimental results from serval subjects, and the results show that the proposed system can achieve more than 95% accuracy rate of heartbeat and breathing number.
