Vital sign simulation system and method for radar life detector

The invention discloses a vital sign simulation system and method for a radar life detector. The system mainly comprises a thorax model, a breathing simulation part, and a control part, wherein the thorax model is provided with a plurality of movable rib simulation assemblies, the breathing simulation part is arranged in the thorax model, is in driving connection with the plurality of movable ribsimulation assemblies in the thorax model, and can drive the plurality of movable rib simulation assemblies to perform up-and-down fluctuating motion so as to simulate the fluctuating motion of the thorax when a human body breathes, and the control part is in control connection with the breathing simulation part so as to control the breathing simulation part to drive a plurality of movable rib simulation assemblies to carry out up-and-down fluctuating motion states so that fluctuation motion of thorax of a human body during breathing in different states can be simulated. Compared with the prior art, the system provide
