A dynamic indemnifying method is used behind the transducer to improve transducer's performance.The principle of normal frequency domain dynamic correction method and its existing problems are also introduced in this paper,and the method of getting compensation segmert's frequency response function is also discussed.The dynamic compensation digital filter's designing method and criterion for dynamic error are discussed.According to typical transducer's dynamic calibrated data,least square method based on volsh function is used to obtain the transducer's transfer function.The corresponding dynamic indemnifying digital filter is designed and the simulation calculation is made by computer.
