Abstract
The invention discloses a long-distance life signal monitoring method based on multiple channels, and the method comprises the following steps: S1, obtaining and preprocessing echo signals of multiple channels of a human body, and merging the preprocessed echo signals of the multiple channels; s2, life signals in distance units are detected according to the combined echo signals, and a vital sign distance unit set containing a plurality of distance units is obtained; s3, calculating according to the vital sign distance unit set to obtain a vital sign phase signal; and S4, decomposing the vital sign phase signal into a plurality of components, analyzing a respiration signal component and a heartbeat signal component, and performing calculation to obtain the respiration frequency and the heartbeat rate of the human body. According to the invention, high-accuracy remote life signal monitoring is realized.
