中文摘要:
      在水声应用领域中,通常是若干个换能器组成一个基阵进行工作。当换能器基阵工作时,基阵中单个换能器的总辐射阻抗是它自身辐射场的作用以及基阵中其它换能器辐射场作用的总和,这就引入了互辐射阻抗的问题。在水声对抗中,当换能器基阵在大功率状态下工作时,基阵的互辐射阻抗影响尤其需要进行研究分析。结合理论推导得出的规律,介绍了一种研究互辐射阻抗的测量分析方法,分析了一种换能器基阵的互辐射阻抗影响,并最终得到一般性结论。
英文摘要:
      An array composed of several transducers is often used in underwater acoustic applications.When the transducer array works,the radiation impedance of every transducer in the array is the summation of the functions of its radiation acoustic field and other transducers'.This relates to the question of mutual radiation impedance,which needs to be considered in underwater acoustic countermeasure,especially when the transducer array works at the state of high power.Combining with the theoretical derivation,a measurement and analysis method of mutual radiation impedance is introduced,and the analysis with a general conclusion of the effect of mutual radiation impedance on transducer array is made.
