Abstract
In radar heartbeat signal detection based on PRT model shaping, a vital-sign signal including a heartbeat component and a respiration component is detected by a radar and sent to a computing device which is electrically connected to the radar, the computing device extracts the heartbeat component from the vital-sign signal to obtain a radar heartbeat signal and segments the radar heartbeat signal into two or more one-cycle radar heartbeat signals, and the computing device multiply each of the one-cycle radar heartbeat signal with a PRT model and connects the one-cycle radar heartbeat signals as a shaped radar heartbeat signal.
Claims17
A radar heartbeat signal detection based on PRT model shaping comprising the steps of:
- detecting a vital-sign signal by a radar, the vital-sign signal includes a heartbeat component and a respiration component;
- receiving the vital-sign signal and extracting the heartbeat component in the vital-sign signal to obtain a radar heartbeat signal by a computing device which is electrically connected to the radar;
- segmenting the radar heartbeat signal into a plurality of one-cycle radar heartbeat signals by the computing device;
- and
- multiplying each of the plurality of one-cycle radar heartbeat signals with a PRT model and connecting the plurality of one-cycle radar heartbeat signals to obtain a shaped radar heartbeat signal by the computing device.
