Abstract

The invention discloses a respiratory and heartbeat signal detection method and device. The method includes the following steps: obtaining echo signals reflected when electromagnetic wave signals emitted by a radar encounter obstacles; extracting target echo signals from the echo signals, wherein the target echo signals are the signals reflected when the electromagnetic wave signals encounter the chests of human bodies; extracting the respiratory signals and heartbeat signals of human bodies from the target echo signals; and determining the respiratory frequencies of the human bodies according to the respiratory signals, and determining the heartbeat frequencies of the human bodies according to the heartbeat signals. Thus, the technical problems of low accuracy rates of existing human body respiratory and heartbeat detection methods can be solved.

Description

technical field [0001] The present application relates to the field of radar target recognition, and in particular, to a method and device for detecting respiratory and heartbeat signals. Background technique [0002] The radar transmits electromagnetic waves to the surface of the target and receives the echo. The distance between the target and the radar will be reflected in the delay of the echo. According to the type of transmitted signal, it can be divided into two categories: pulse radar and continuous wave radar. Conventional pulse radar transmits periodic high-frequency pulses, and continuous wave radar transmits continuous wave signals. The continuous wave radar can realize distance measurement and speed measurement by transmitting frequency-modulated continuous wave signal. The FM continuous wave radar transmits continuous waves with changing frequency during the frequency sweep period. The echo emitted by the object has a certain frequency difference from the tran...
