摘要
针对会聚区目标判定缺乏有效的特征判据问题,论文给出了一种利用参数a、b、c作为会聚区声场特征因子表征会聚区声场的方法,通过理论分析及仿真计算,当用a,b,c三参数来描述声场的水平特征时,a,b,c三参数有明确的物理意义,计算出的声场传播损失和用kraken软件计算出的结果吻合良好,说明声场参数化表征方法可很好地描述会聚区声场特征。在实际应用中,如能够根据实际会聚区声场特征,获得特征因子a、b、c,表征会聚区与非会聚区声场特征差异,可为会聚区的判定提供参考标准。
For the question of judging the target is in convergence zone,this paper gives a method of parameterized characterization for acoustic field convergence zone using three parameters a,b,c. Through theoretical analysis and simulation calculation,when using three parameters a,b,c characterize acoustic field of convergence zone,three parameters have the definite meaning.And calculated TL is in accordance with the kraken software. It illustrates that the method is feasible to characterize the acoustic field. In fact,if the parameters can be gotten according to the practical acoustic field of target,characteristics differences of convergence zone and non convergence zone can be deseribed. Three parameters can be used as the basis for judging target in the convergence zone.
