Abstract

This study presents a probabilistic one-step two-dimensional (2D) inversion method of spherical-wave reflection coefficient data to estimate the range-dependent structure and geoacoustic parameters along a track. The approach of inverting such datasets independently as one-dimensional (1D) layered models and merging them to a 2D section is feasible but computationally expensive. This study demonstrates a more parsimonious 2D parametrization for active source data recorded on a towed hydrophone array. The comparison of data variance reduction for 1D- and 2D-based results clearly favors the 2D parametrization described here.

距离相关的中尺度海底地声定量。
提出了球波反射系数数据的概率一步二维反演方法,以估计轨道上的距离相关结构和地声参数。将这些数据集独立地反演为一维(1D)分层模型并将其合并到二维剖面的方法是可行的,但计算成本很高。本研究演示了拖曳式水听器阵列上记录的有源数据的更简洁的二维参数化。基于一维和基于二维结果的数据方差减少的比较显然有利于这里描述的二维参数化。
