论文摘要
我们提出了一种通过在贝叶斯信息标准的背景下将步入式垂直地震分析数据与多层模型进行比较,以选择弹性参数值的策略。我们考虑$ p $ - 波旅行时间,并假定椭圆速度依赖性。贝叶斯信息准则方法需要两个优化步骤。在第一步中,我们找到了信号轨迹,在第二步中,我们通过最大程度地减少模型和数据之间的不合适来找到媒体参数。
We present a strategy for selecting the values of elasticity parameters by comparing walk-away vertical seismic profiling data with a multilayered model in the context of Bayesian Information Criterion. We consider $P$-wave traveltimes and assume elliptical velocity dependence. The Bayesian Information Criterion approach requires two steps of optimization. In the first step, we find the signal trajectory and, in the second step, we find media parameters by minimizing the misfit between the model and data.
