Abstract :
In this paper, the application of fixed-frequency and multifrequency radiowave interferometry using magic tee and Gunn-diode autodyne for detection of human respiratory shifts and heartbeats is presented. The methods, which provide remote detection of thorax shifts, caused by respiratory movements and heartbeats, are implemented; amplitudes and frequencies of respiratory movements and heartbeats are measured
