If the obstacle encountered is stationary, the returned electromagnetic wave signal will not change, but once a moving target is encountered, such as various fluctuations caused by human life activities, such as breathing and heartbeat, the reflected electromagnetic wave signal will have a certain frequency shift according to the moving speed.
