Signal calibration instrument mechanical vibration device for testing life detection radar performance

The invention provides a signal calibration instrument mechanical vibration device for testing the life detection radar performance, which belongs to the technical field of radar detection and comprises a vibration body, an electric conical component, a transmission rod, a metal vibration surface, a laser position indication component and a displacement sensor, wherein the electric conical component is fixed on the vibration body, one end of the transmission rod is fixed on the electric conical component, the other end of the transmission rod is fixed on the metal vibration surface, the laserposition indication component is arranged on the metal vibration surface, and the displacement sensor is arranged on the transmission rod. Signals output by a driving circuit are received through thevibration body, then, the electric signals are converted into the mechanical vibration of the transmission rod, the front metal vibration surface is driven to vibrate, the laser position indication component is used for aiming at the geometric center of the detection surface of a radar detection instrument, the vibration signals of the vibration body can be obtained through the displacement sensor arranged on the transmission rod, the structure is simple, and the application range is wide.
