A method for health monitoring, comprising: transmitting an Amplitude Modulated Continuous Wave (AMCW) microwave signal towards a subject being monitored, by a monitoring system, wherein the AMCW signal comprises a Continuous Wave microwave signal as a carrier signal along with a modulating signal; capturing the AMCW microwave signal when the AMCW microwave signal is reflected from the subject, by the monitoring system, wherein the modulating signal of the reflected AMCW microwave signal carries a measured heart rate and a measured breathing rate of the subject; extracting the modulating signal from the captured AMCW signal, by the monitoring system; mixing the extracted modulating signal with a reference modulating signal to generate a first mixed signal, by the monitoring system, wherein the reference modulating signal is the modulating signal that is transmitted towards the subject; mixing the extracted modulating signal with the quadrature of the reference modulating signal, by the monitoring system, to generate a second mixed signal; capturing relative phase shift of the modulating signal in the first mixed signal and in the second mixed signal to generate a relative phase shift signal, by low pass filtering the I and the Q and by taking Arctan on ratio of output of the low pass filtering of the I and the Q, by the monitoring system; and extracting a first component and a second component from the generated relative phase shifted signal, by the monitoring system, wherein the first component represents the measured heart rate and the second component represents the measured breathing rate of the subject. transmitting an Amplitude Modulated Continuous Wave (AMCW) microwave signal towards a subject being monitored, by a monitoring system, wherein the AMCW signal comprises a Continuous Wave microwave signal as a carrier signal along with a modulating signal; capturing the AMCW microwave signal when the AMCW microwave signal is reflected from the subject, by the monitoring system, wherein the modulating signal of the reflected AMCW microwave signal carries a measured heart rate and a measured breathing rate of the subject; extracting the modulating signal from the captured AMCW signal, by the monitoring system; mixing the extracted modulating signal with a reference modulating signal to generate a first mixed signal, by the monitoring system, wherein the reference modulating signal is the modulating signal that is transmitted towards the subject; mixing the extracted modulating signal with the quadrature of the reference modulating signal, by the monitoring system, to generate a second mixed signal; capturing relative phase shift of the modulating signal in the first mixed signal and in the second mixed signal to generate a relative phase shift signal, by low pass filtering the I and the Q and by taking Arctan on ratio of output of the low pass filtering of the I and the Q, by the monitoring system; and extracting a first component and a second component from the generated relative phase shifted signal, by the monitoring system, wherein the first component represents the measured heart rate and the second component represents the measured breathing rate of the subject.
