Ultrasonic transducer for the transmission properties change with temperature and pressure of this common problem, using adaptive filtering techniques on the ultrasonic transmission characteristics of the transducer be calibrated to reduce the temperature and pressure changes on signal detection impact. Real data processing results show that: Based on RL S method of adaptive filtering techniques can accurately calculate temperature and pressure conditions at different transducer changes in transmission characteristics of the inverse function, which can be corrected well as transmission characteristics of ultrasonic transducer With the introduction of temperature and pressure changes in the signal error.
