Title:
心拍周期測定装置及び心拍周期測定プログラム
Document Type and Number:
Japanese Patent JP7224163
Kind Code:
B2
Abstract:
To enable a cardiac cycle to be measured even when there is a variation in a waveform interval of a time series change in a radar signal in measuring a cardiac cycle based on a result of correlation processing of the time series change in the radar signal.SOLUTION: A cardiac cycle measuring device 2 includes: a heartbeat component extraction part 23 for removing a respiratory component and extracting a heartbeat component for a time series change in a radar signal irradiated onto a living body surface V and reflected from the living body surface V; a correlation processing execution part 24 for executing correlation processing with a plurality of types of signal time lengths for a time series change in the radar signal from which the heartbeat component is extracted; and a cardiac cycle measuring part 25 for measuring a correlation peak time as a cardiac cycle in at least any one of correlation processing results with a plurality of types of signal time lengths.SELECTED DRAWING: Figure 3
