In the research of life characteristic signal processing, because of different status, postures and positions, the results produce huge difference. Therefore, this paper designs a monitoring system which is based on biological radar simulation system, and it could be used in the study of life cha-racteristic signal. The system provides target signals with stable quantitation for the research of life characteristic signal processing, and the signal parameters such as frequency, amplitude are adjustable. The system realizes the non-contact life detecting experiment through simulating the cardio of human. Through the test of the simulation system under different conditions, the expe-rimental results prove that under different conditions, the system has better SNR and is globally stable, improving the practicability.
