Abstract
There is provided an FMCW radar target detection method for vital signal detection. A method for detecting vital signals by using radar selects a range bin where there are accurate vital signals by using a correlation between a phase change profile of an IF signal caused by a minute motion, and a target signal intensity change profile, so that accuracy of estimation of vital signals can be enhanced through exact tracking of a person (target). In addition, clutter may be exactly removed by utilizing a phase unwrapping technique which is adaptive to an upper body motion change compared to a 180-degree fixed phase unwrapping technique.
