Title:
ELECTRONIC APPARATUS, METHOD FOR CONTROLLING ELECTRONIC APPARATUS, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/058226
Kind Code:
A1
Abstract:
This electronic apparatus comprises: a transmission unit which transmits a transmission wave; a reception unit which receives a reflection wave from a target of the transmission wave; and a signal processing unit which detects the distance, the direction, and the velocity of the target on the basis of transformed signals after beat signals of the transmission wave and the reception wave are Fourier-transformed. The signal processing unit: extracts, from the transformed signals, signal components corresponding to a heart sound vibration accompanying the heart beat of the target by means of a plurality of window functions; performs a frequency analysis on the envelope signal obtained by performing envelope processing on the signal components corresponding to the heart sound vibration; calculates a statistical result with respect to the frequency analysis result; and outputs, on the basis of the calculation result, time series data of the heart beat frequency of the target.
