  • 摘要: 地基干涉合成孔径雷达(Ground-Based Interferometric Synthetic Aperture Radar, GB-InSAR)技术凭借其全天时、全天候以及长时间稳定连续工作等独特的优势,在矿山边坡监测、地质灾害监测、建筑物健康监测以及灾害预警等诸多领域展现出了广泛的应用前景。尽管该技术已取得一定的成果,由于相关真实数据未能公开,这限制了地基雷达技术的创新发展。针对上述问题,本文公开了GB-InSAR实测场景成像及形变提取数据集。该数据集包含地基雷达采集同一场景、不同距离放置多点角反射器场景的回波数据、成像数据和相干性数据,同时具备标准体和实测场景的GB-InSAR全流程数据。通过对这些数据的深入分析,可以实现对数据的多维度研究。在雷达成像方面,可依据雷达分辨率的成像性能指标进行分析。通过分析相干系数数据探究目标在不同时间或空间的一致性,为目标识别和监测提供更精准的方法。该数据集不仅验证了GB-InSAR监测技术的可靠性和稳定性,而且通过应用案例,展示了GB-InSAR监测技术能力可以达到亚毫米精度级别,为实现对建筑物和地表微小形变实时监测提供有力的技术手段。本数据集充分考虑了雷达成像、系统稳定性等雷达信号处理方法研究对实测数据的需要,为相关学者提供多元化的数据资源。此外,基于这些数据还可以开展形变分析,为结构体健康监测和灾害预警提供有力的数据支持。

     

    Abstract: ‍ ‍Ground-based interferometric synthetic aperture radar (GB-InSAR) technology, owing to its unique advantages of all-day, all-weather operation as well as long-term stable and continuous operation, presents broad application prospects in numerous fields, including mine-slope monitoring, geological disaster monitoring, building health monitoring, and disaster early warning. Although certain achievements have been realized using this technology, the non-disclosure of relevant actual data limits the innovative development of ground-based radar technology. Hence, this paper publicly discloses a dataset of GB-InSAR real-scene imaging and deformation extraction. This dataset includes echo, imaging, and coherence data obtained using ground-based radar for the same scene and for scenes with multiple corner reflectors placed at different distances. Additionally, it includes full-process GB-InSAR data for both standard bodies and actual measurement scenes. Based on a comprehensive analysis of these data, multidimensional research on the data can be performed. In terms of radar imaging, analysis is performed based on imaging performance indicators, such as radar resolution. By analyzing the coherence coefficient data, the consistency of the target at different times or spaces is investigated, thus providing a more accurate method for target recognition and monitoring. This dataset not only verifies the reliability and stability of the GB-InSAR monitoring technology but also shows that the monitoring technology of GB-InSAR can reach the millimeter or even submillimeter accuracy level, thereby providing an effective method for monitoring minimal deformations of buildings and the Earth’s surface in real time. This dataset fully considers the demands of studies pertaining to radar signal-processing methods, such as radar imaging and system stability, for actual measurement data and provides diversified data resources for relevant scholars. Additionally, deformation analysis can be performed based on these data, thus providing robust data support for the health monitoring of structures and disaster early warning.
