| 摘要: |
| 浅地层剖面技术是应用声学原理高效获取海底面之下浅部地质地球物理信息的探测技术，主要应用于海底浅地层信息探测和海底特殊目标调查等方面。以往研究者主要集中在浅地层剖面的具体应用，未对不同类型的浅剖应用效果进行综合对比分析，本文比较4种不同类型浅地层剖面系统的组成、工作方式和探测技术参数，认为不同尺度的探测目标需要应用不同类型的浅地层剖面系统。分析和对比不同震源类型浅剖的应用案例，发现电火花震源穿透能力最强，分辨率随工作频率的增大而提高；电磁式震源穿透深度与分辨率适中；压电换能器震源分辨率较高，穿透能力弱；参量阵震源利用差频原理，信号中包含高频与低频两部分，能够同时得到较高的分辨率与较大的穿透深度。未来浅地层剖面探测技术向深穿透、高分辨率、高效率、二维向三维甚至高维探测方面发展。 |

| Abstract: |
| The sub-bottom profiler (SBP) is a sounding technology that can efficiently obtain shallow geological and geophysical information from under the seabed based on the principle of acoustics. SPBs are mainly used in the explorations of the seabed strata and the investigation of special submarine targets. While early SPB users and researchers focused mainly on the practical application of the SBP, they did not compare or analyze application performance of different types of SBPs. In this paper, we compare the composition, workflow, and exploration associated with the technical parameters of four different types of SBPs. Our findings indicate that different SBP types are suitable for exploring different targets under different conditions. Based on our analysis and comparison of applications specific to different source types, we determined that the transmission ability of the Sparker source is the strongest, its resolution increases with increases in the working frequency, and its electromagnetic-source penetration depth and resolution are moderate. The resolution of the piezoelectric transducer is high, but its penetrability is weak. Parametric sources with both high- and low-frequency aspects can ensure a certain penetration depth with high resolution. In the future, the development of SBP exploration technology will be able to achieve deeper penetration, higher resolution, higher efficiency, and three-dimensional or even high-dimensional capability. |
