摘要

介绍了一种基于微波多普勒技术的心跳检测系统。使用矢量网络分析仪，测试了微波系统在距离人1英尺处检测心跳信号的能力。该系统具有检测心跳信号的能力，并具有调节辐射功率的可能性。测量在10dbm, 0dbm， -10dbm， -15dbm和-25dbm进行。基于对呼吸和心跳的测量，提出了一个代表心肺活动的信号。利用小波滤波和经典滤波对信号进行了心率和心率的提取。

An analysis of vital sign using microwave Doppler technique

This paper presents a system for hearbeat detection using microwave Doppler technique. Using a vector network analyzer, a microwave system is tested for the detection of the heartbeat signal at a distance of 1 feet from a person. The proposed system shows the ability of detecting the heartbeat signals with the possibility of tuning the radiated power. Measurements are performed at 10dbm, 0dbm, -10dbm, -15dbm and -25dbm. Based on measurements perform for respiration and heart beatings, a signal representing the cardiopulmonary activity is presented. The heartbeat rate and heart rate are extracted from the signal using wavelet and classic filters.
