本論文提出一毫米波雷達系統，以非接觸式的方法偵測人體震動，使用所設計之演算法計算心率以及呼吸率，並且驗證其準確性。所使用之雷達波段為60GHz至64GHz之毫米波雷達波段，應用頻率調變連續波雷達技術，對微小震動十分敏感，因此能夠收集胸腔上的微小震動。由於心跳與呼吸的振幅及頻率不同，可以使用濾波器將兩者分離，分別處理計算心率及呼吸率。心率可以藉由模擬心電圖中的PQRS波形特性，尋找R波，計算心率。驗證毫米波雷達系統演算法非常繁雜卻十分重要，最終試驗分成多個部分，最重要且收集最多資料的正躺測試，以及蓋被測試、側躺測試、翻身測試及離床測試等，結果顯示，心率平均誤差率在5\%以內，呼吸率的誤差在2RPM以內，並且不受衣物及被子影響，在不同睡姿也能得到正確數據，姿勢變換後三十秒內能重新計算出正確心率以及呼吸率。

A millimeter-wave radar system is proposed to countlessly detect human chest vibration and use the designed algorithm to calculate heart and respiration rates. The bandwidth of the radar is 60 GHz to 64 GHz millimeter -wave. Frequency modulation continuous wave radar technology is adapted, which is very sensitive to tiny vibrations to collect the small vibrations on the chest cavity. Since the amplitude and frequency of heartbeat and respiration are different, the heart rate and respiration rate can be calculated separately. Heart rate can be calculated by simulating the characteristics of the PQRS waveform in the electrocardiogram and calculating the number of R-R intervals. Verifying the millimeter-wave radar system algorithm is very complicated but very important. The final test is divided into several parts: the most necessary and most data-collected lying test and the cover test, side-lying test, rollover test, and vacancy test. The results show that The average heart rate error rate is 5\%, and the average breathing rate error is 2 RPM. Correct data can be obtained even though covered a quilt in different sleeping positions and can be recalculated within 30 seconds after the posture is changed
