摘要

在过去的几年里,商业运营的航天器取得了显著的进步,可重复使用的火箭发动机取得了成功,探索太空的国际竞争也促使设计和准备未来雄心勃勃的月球任务的活动大大加快。在寻找冰和/或空洞的过程中,地表下浅层结构的成像至关重要。因此,以往的研究表明,地震干涉测量法是利用被动月球数据研究地表下特性的一种很有前途的方法。在本研究中,我们希望通过研究地震测量所需的持续时间以及散射对格林函数检索的影响,进一步评估这种方法的潜力。因此,我们将地震干涉测量法应用于阿波罗 17 号的测量数据和合成数据。我们的研究结果表明,在最佳条件下,使用时间尺度相位加权叠加(ts-PWS)方法,几个小时的数据就足够了。然而,这在很大程度上取决于站间距离、主要噪声源的方向以及月球周期中的测量时间。此外,我们还利用二维数值模拟重现了测量数据。合成结果表明,散射效应明显影响了格林函数的提取,尤其是在测站距离较大的情况下。

Investigating Subsurface Properties of the Shallow Lunar Crust Using Seismic Interferometry on Synthetic and Recorded Data

Investigating Subsurface Properties of the Shallow Lunar Crust Using Seismic Interferometry on Synthetic and Recorded Data

In the past few years, the remarkable progress of commercially operated spacecrafts, the success with reusable rocket engines, as well as the international competition to explore space, has led to a substantial acceleration of activities in the design and preparation of ambitious future lunar missions. In the search for ice and/or cavities imaging the shallow subsurface structure is of vital importance. Hereby, previous studies have shown that seismic interferometry is a promising method to investigate the subsurface properties from passive lunar data. In this study, we want to evaluate the potential of this method further by examining the required duration of seismic measurements and the influence of scattering on the Green's function retrieval. Therefore, we applied seismic interferometry to both measured Apollo 17 data and synthetic data. Our findings indicate that, under optimal conditions, a few hours of data are sufficient when using the method of time-scaled phase-weighted stack (ts-PWS). However, this strongly depends on the inter-station distance, the orientation toward the principal noise sources, and the timing of the measurement during the lunar cycle. Additionally, we were able to reproduce the measured data using numerical simulations in 2D. The synthetic results show that scattering effects clearly influence the Green's function extraction, especially for larger station distances.
