Abstract
A method and system for detecting at least one of a heart rate and a respiratory rate of a subject are disclosed. In one aspect, the method includes transmitting a signal towards the subject and receiving a reflected signal from the subject being Doppler-shifted due to at least one of the heart rate and the respiratory rate. The method also includes providing the reflected signal to a first input of a phase comparator, providing an adjustible reference signal to a second input of the phase comparator, and generating an output signal by the phase comparator based on the reflected signal and the reference signal. The method includes varying, by the reference signal generator, at least one of a phase and a frequency of the adjustable reference signal based on the output signal of the phase comparator to track a phase of the reflected signal.
