摘要
干涉雷达(interferometric synthetic aperture Radar, InSAR)技术以其全天候、全天时以及高空间分辨率的优势已在多个领域得到广泛应用,并展现出极强的适应性与实用价值。通过对甘肃省舟曲县2个典型滑坡区域的小基线集合成孔径雷达(small baseline subset InSAR,SBAS-InSAR)监测结果以及卡尔曼滤波预测结果与全球导航卫星系统(Global Navigation Satelhite System, GNSS)监测数据进行对比,验证了SBAS-InSAR技术在滑坡变形监测中的可靠性和准确性。结果显示,SBAS-InSAR在滑坡变形监测中展现了高度的准确性和可信度。这一技术在地质灾害形变区域的显著优势有效补充了传统监测手段的不足,为舟曲县及其他地质灾害频发地区的灾害预警和管理提供了关键的技术支持和科学依据。
Given its all-day availability,all-weather adaptability,and high spatial resolution,the interferometric synthetic aperture radar(InSAR)technique has been widely applied in multiple fields,demonstrating strong adaptability and high practical value.Focusing on two typical landslide areas in Zhouqu County,Gansu Province,this study compared small baseline subset InSAR(SBAS-InSAR)monitoring results and Kalman filter prediction results with monitoring data from the global navigation satellite system(GNSS),confirming the reliability and accuracy of the SBAS-InSAR technique in monitoring landslide deformations.The results indicate that the SBAS-InSAR technique exhibited significant advantages in monitoring areas with deformations induced by geologic disasters,effectively overcoming the limitations of traditional monitoring means.This technique can provide critical technical support and scientific basis for early warning and management of geologic disasters in Zhouqu County and other areas prone to suffer these disasters.
