Abstract:
A dynamic indemnifying method is used behind the t ransducer to improve transducer’ s performance. T he principle of normal f requency domain dynamic correction method and it s existing problems are also int roduced in this paper, and the method of g et ting compensation segmert. s f requency response funct ion is also discussed. T he dynamic compensat ion digital f i-l te r’s designing method and criterion for dynamic error are discussed. According to ty pical transducer. s dynamic calibrated data, least square method based on volsh funct ion is used to obtain the transducer’s transfer funct ion. The corresponding dynamic indemnifying digital filter is designed and the simulat ion calculat ion is made by computer.
