分层海底参数分布反演稳定性判据实验验证

An experimental verification of the stability criterion of inverse algorithms for layered sea bottom

摘要: 本文采用两种反演算法对工厂冷却水池模拟实验数据进行声场反演,其反演误差急剧增长均出现数值发散现象。根据反演稳定性判据将记录数据略加修正后,两种反演的稳定性明显改善,其反演结果基本与实测数据相符。

Abstract: In this paper,two inverse algorithms were used to infer the impedance profile of the layered bottom in the cooling-water pool of a paint factory.The error made by two algorithms increases trementously that leads to overflow in computation.Bioth inverse results are quite close to the measured data if the recorded data are con cted by the stability criterion.
