Signal generating device for life detection radar performance calibration

The utility model discloses a signal generating device for life detection radar performance calibration. The signal generating device comprises a box body, a mounting bracket, a linear motion module, a reflecting plate and a counter, the battery is installed in the box body, the installation support is fixedly connected in the box body, the linear motion module is connected with the installation support, the reflecting plate is detachably connected with a reciprocating motion component of the linear motion module, and the counter is arranged at the stroke tail end of the reciprocating motion component and used for recording the reciprocating motion frequency of the reflecting plate. The motor drives the lead screw to rotate so as to drive the reflecting plate to reciprocate, operation is stable, noise is avoided, meanwhile, great vibration is avoided, and it is guaranteed that the device is placed stably. The reflecting plates are detachably connected with the sliding blocks, and the sizes of the heart and th
