According to the application requirements of radar life detector calibration test and practical training, this paper studies the vital sign simulation device for radar life detector. The device realizes the simulation of breathing and heartbeat movement of buried pressure personnel at different stages, and has real human chest curve and anatomical marks. It can not only meet the accurate and rapid test requirements of the laboratory, but also adapt to the complex and harsh ruins drill site. Through the development of this simulation system, it provides a test object to help the existing radar life detector improving the accuracy of weak vital signs signal detection, and also provides technical support for the fire brigade to effectively carry out the search and rescue training exercise of personnel in buried pressure.
