Abstract

This article is launched based on the target that to research the forecasting method of transducer state. Generally, the receive array of sonar is made up of several transducers according to one certain way, when the damaged quantity or degree of transducer reaches a specified level, there will have a great effect on the receive directivity of sonar, so that it needs to replace new transducer units. Up to now, there is no uniform forecasting method of transducer state. This article has implemented a new forecasting method of transducer state based on the performance estimate of the array: Firstly, the influence of insulation resistance is introduced into beamforming through ensuring the mathematic relationship between insulation resistance, working frequency and beamforming weighted coefficient of transducer; Secondly, after comparing sampling with standard of beam, technical factors is found to justice whether the beam directivity satisfy the requirement; Finally, to start transducer replacement, the status of it is estimated by investigating these index. The experiment result indicates that this method is effective.
