Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0033] Human breathing and heartbeat signal detection technology based on UWB (Ultra Wide Band: ultra-wide band) radar system can detect the human body in a certain area, across certain media (such as walls, clothing, etc.) and without touching the target. The technology of detecting and extracting the breathing and heartbeat signal of the device has the advantages of remote monitoring, strong penetrability, strong anti-interference ability, high precision, and non-contact. However, since the UWB radar system will be interfered by the noise of the external environment, and the strength of the human body's breathing and heartbeat signal is weak, the randomness of the signal received by the radar will be strong, which will increase the echo signal in the low signal-to-noise ...

Abstract

The invention discloses a human body breathing and heartbeat signal detection method and system based on UWB (ultra wide band) radar. The method comprises the following steps: the UWB radar transmitssignals to a human body; the UWB radar receives a target echo signal, and a two-dimensional echo data matrix is obtained after the target echo signal is processed; a direct current component is removed from the two-dimensional echo data matrix, and windowing pulse pressure processing is carried out along the distance direction to obtain a preprocessed matrix; fixed clutters of the preprocessed matrix are removed, and target distance locking is completed through constant false-alarm rate detection; and a weight vector is introduced, and sparse reconstruction is completed through an OMP algorithm to obtain target breathing and heartbeat signals. The human body breathing and heartbeat signal detection method and system based on the UWB radar can accurately extract and separate respiration andheartbeat signals from the echo signals so as to realize non-contact heartbeat and respiration monitoring of the human body.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband radar, in particular to a method and system for detecting human breathing and heartbeat signals based on UWB radar. Background technique [0002] The two vital signs of the human body, heartbeat and respiration, can accurately understand the physiological condition of the human body. At present, the monitoring of human heartbeat and respiration in clinical medicine in my country is largely realized through contact inspection instruments, such as: electrocardiogram, breathing strap, etc. Belts, stethoscopes, etc. For those patients who need to be monitored for a long time or patients with large area burns and skin allergies, contact monitoring methods cannot be used. Contents of the invention [0003] The present invention provides a method and system for detecting human breathing and heartbeat signals based on UWB radar, which can accurately extract and separate breathing signals and hear...
