基于多步优化策略的地声参数反演方法与研究

摘要

The same cost funciton for different frequencies were selected by the traditonal inversion method of geoacoustic parameters.This paper presents a new strategy for inverting geoacoustic properties,which using different cost function and signal frequency to different properties.The result proves the effectiveness of strategy.%传统的地声参数多步优化反演方法大多选用同一代价函数对不同频段进行反演。文章提出一种新的地声参数反演多步优化策略,针对不同参数选择不同类型的代价函数和信号频段,并应用于某海试实验数据处理,验证了其有效性。
