Abstract As the measuring noise is the main factor that affects the dynamic compensation effect of sensor, and the ideal compensation effect of sensor within noisy environment is studied. The method to determine the ideal frequency bandwidth of the sensor after dynamic compensation according to measurement noise is proposed, as well as the method to determine the ideal value of time-domain performance index including adjusting time and overshoot through the ideal frequency bandwidth. The proposed method is applied to the dynamic calibration experiment of the strain gauge balance, its effectiveness is verified. Finally, the method is used to assess that the strain gauge balance after dynamic compensation could meet the requirements of the wind tunnel test of the aircraft. That shows the method could be used to determine whether the sensor after dynamic compensation is suitable for the dynamic test.
