Inversion for sound speed profile in shallow water using matched-beam processing

  • 摘要: 为了快速反演获得浅海声速剖面,利用匹配波束构造了反演代价函数,在此基础上研究了浅海声速剖面的匹配波束反演方法(MBI)。并运用东中国海的实验数据进行实际反演,验证了MBI的可行性和鲁棒性。利用垂直线列阵接收的29个不同位置的爆炸声信号进行了声速剖面反演,MBI反演的结果与实验中直接测量的声速剖面一致,且反演声速剖面的均方根误差小于2 m/s。研究结果表明,MBI比常规匹配场反演(MFI)获得浅海声速剖面更快速、更准确,并且对底质参数的失配具有较高的鲁棒性。
    Abstract: To quickly obtain the sound speed profile (SSP) in shallow water by inversion methods, an inversion scheme for SSP in shallow water using Matched-Beam Inversion (MBI) is developed. The cost function of MBI is based on matched-beam concept. It is verified experimentally that MBI is feasible and superior in comparison to conventional matched-field inversion (MFI) by using the East China Sea Experiment data. The SSP inverted by MBI using the wide-band explosion signals is in good agreement with the results based on Conductivity, Temperature and Depth, (CTD) measured in the experiment. And the root of mean square error of the SSP is less than 2m/s. Research results have shown that MBI is robust with respect to the sediment parameters mismatch. And SSP in shallow water can be more quickly obtained by MBI than by MFI.
