雅鲁藏布江中下游沉积结构探地雷达探测数据（2020-2024）

本数据为雅鲁藏布江河流沉积结构探地雷达探测数据，该数据记录了电磁波经浅地表沉积物反射后的振幅和走时等信息，从而揭示沉积物层理、厚度变化及下伏地质界面特征。数据通过人工采集的方式获得，经过去噪、滤波、增益校正及时间-深度转换等处理后，确保了较高的精度与信噪比。结果显示，该数据实现了雅鲁藏布江浅部沉积结构的高分辨率成像，为研究河流演化、沉积动力学提供了重要依据，并为未来开展精细沉积结构分析与河道工程规划奠定了数据基础。

This dataset consists of ground-penetrating radar (GPR) detection data of fluvial sedimentary structures in the Yarlung Zangbo River. It records information such as the amplitude and travel time of electromagnetic waves reflected by shallow subsurface sediments, thereby revealing the sedimentary bedding, thickness variations, and characteristics of underlying geological interfaces. The data was manually collected, and processed with denoising, filtering, gain correction, time-depth conversion and other procedures, ensuring high accuracy and signal-to-noise ratio (SNR). The results demonstrate that this dataset has achieved high-resolution imaging of shallow sedimentary structures in the Yarlung Zangbo River, providing an important basis for research on fluvial evolution and sedimentary dynamics, and laying a data foundation for future refined sedimentary structure analysis and river channel engineering planning.
