A interpolation method for vital signs using doppler radar sensing

摘要

The invention of the human body to breathe through the microwave transmitting and receiving the body, the heart rate signal based on the Doppler effect, It will remove the effect of the obtained heart rate signal and respiration of the HRV (eyichial V) interpolation method using the Doppler radar for the heart rate data for analyzing the body condition of the circulatory system, such as health, stress level of the body. ; The present invention includes the steps of measuring the respiratory signal of the heart rate signal to the human body non-contact using a Doppler signal of the microwave, the Doppler signal from the heart rate of heart rate is to be interpolated by the respiration signal to change, standard heart rate using the ECG Doppler heart rate signal with respect to the maximum point of a signal set to a predetermined period with respect to the respiratory cycle in order to interpolate the signal to be fast or slow by breathing signal, multiple-segment the level of the respiratory signal, occurring during the set Doppler respiratory cycle measuring the period between each heart beat signal, and the combined period of the whole regardless of the level of the respiratory signal during the set respiratory cycle Doppler average period measurements, the heart beat cycle of the Doppler signal during the set respiratory cycle so as to interpolate the error occurred and the level of the multiple-segment, and respiratory signals respectively and configured to measure a heart rate signal having the same value respiratory interval size by the Doppler frequency as the average period of the heart rate. ; The present invention is a microwave Doppler and ECG heart rate signal, but compared to the normal heart beat signal cycle, the level of multiple-segment by using the heart rate signal a respiratory signal with the same value so that accurate interpolation errors generated by the breathing signal and reliable HRV has the functions and effects provided by the analysis.
