大探深低频探地雷达勘探数据集

近年来由于我国地铁发展迅速相关地质勘探业务暴涨，但城区勘探受建筑等影响因素众多传统探地雷达不能做到大深度、连续性勘察。大探深雷达针对探地雷达有效测量距离浅和深部目标分辨差的问题，收发天线不再采用一体化、工作频率为高频，选择2MHz的低频磁偶极子、电天降低磁场衰减，设计高精度大动态接收器增加信号测量范围进而提高探测深度。
研制的大探深雷达相对传统检测手段在探测距离达到80m的基础上，保证了深部目标的分辨能力，解决了现有产品测量距离较近的痛点；采用幅度相位联合测量和反演技术，解决了现有产品探测浅的难点；充分考虑恶劣电磁环境和复杂城市空间，具有较强的环境和空间适应性。
大深度雷达主要记录了磁场幅度强度、电场幅度强度、相位差、接幅度比、探测深度等原始观测值，数据量约334.83K。

In recent years, with the rapid expansion of subway construction in China, the scale of related geological exploration businesses has surged. However, urban geological exploration is constrained by multiple factors such as surrounding buildings, and traditional ground penetrating radars (GPR) fail to support large-depth and continuous survey operations. To address the issues of shallow effective measurement distance and poor resolution of deep targets in traditional GPR, the newly developed deep-penetrating GPR abandons the integrated transceiver antenna design. Unlike traditional designs that use high operating frequencies, it adopts a 2 MHz low-frequency magnetic dipole and electric antenna to reduce magnetic field attenuation, and integrates a high-precision, large-dynamic-range receiver to expand the signal measurement range, thereby improving the detection depth. Compared with traditional detection means, the developed deep-penetrating GPR achieves a maximum detection distance of 80 meters while ensuring the resolution of deep targets, solving the long-standing pain point of short measurement distance of existing GPR products. It adopts amplitude-phase joint measurement and inversion technology to overcome the difficulty of shallow detection faced by traditional devices. Fully taking into account harsh electromagnetic environments and complex urban spaces, the system exhibits strong environmental and spatial adaptability. The deep-penetrating GPR mainly records original observation data including magnetic field amplitude, electric field amplitude, phase difference, received amplitude ratio, and detection depth, with a total data volume of approximately 334.83K.
