Nowadays, biometrics using fingerprints, iris and other physical characteristics is gaining attention. This has led to research on biometric identification using heartbeat signals. However, biometrics have been reported to be forged in some cases. Similarly, heart rate signals can be forged as well. In this study, heartbeat waveforms were acquired using 77 GHz FMCW radar, and the acquired waveforms were manipulated using linear actuator. It was then acquired again with 77 GHz FMCW radar and the acquired displacements were compared to the original heartbeat waveforms. The RMSE ranged from 0.12 to 0.20 [mm], with an average of 0.16 [mm], and the error rate ranged from 0 to 7.125 [%], with an average of 4.075 [%]. From this, it was possible to show the possibility that the heartbeat waveform can be simulated by a non-contact biometric authentication system.
