METHOD FOR THE AUTOMATED REMOTE EVALUATION OF PARAMETERS OF HUMAN OR ANIMAL MOTOR ACTIVITY, RESPIRATION AND PULSE

摘要

The invention relates to the field of the automated evaluation of human or animal parameters with the aid of electromagnetic radio signals. The problem of interest is to improve the evaluation of the parameters of respiration, heartbeat and type and intensity of motor activity of a living subject with the aid of electromagnetic signals in the radio-frequency range and to simplify the examination procedure. The method includes receiving a signal reflected from the living subject; processing and analyzing the reflected signal by determining the phase difference stemming from the signal reflected from the subject; and obtaining one or more physiological parameters of the living subject. The method differs in that it additionally includes identifying types of movement of the subject, for which purpose a probing signal with stepped frequency modulation is used, and a coherent square receiver is used as the receiver of the signals reflected from the subject. The probing signal is formed as bursts of partial frequency components in the gigahertz range. The method stages are as follows: 1) selecting the probing frequency optimum for the position of the subject relative to a transceiver unit of a device; 2) analyzing the recordings obtained for each of the probing frequencies; 3) breaking down the signal recording into intervals between the periods corresponding to the movements of the living subject; 4) determining the parameters of respiration and cardiac activity.
