星载InSAR技术城市建筑形变监测

On-board InSAR technology urban building deformation monitoring

为了更深入研究大区域范围内、建筑物形变机理,并在灾害发生前进行实现预警,需要进行全覆盖、长时间、连续、实时和高精度的形变监测。随着卫星遥感技术的发展,由于具备高精度形变监测能力,作为形变监测重要手段的InSAR(Interferometric Synthetic Aperture Radar,InSAR)技术得到了迅猛的发展,并逐渐走向成熟和应用,在形变监测中得到了重视和应用。以北京市的某酒店为试点,将实测水准结果与InSAR测得的数据进行对比,分析In SAR在不同条件下的形变测量精度。

In order to further study the deformation mechanism of large areas and buildings,and to realize early warning before disasters occur,full coverage,long time,continuous,real-time and high-precision deformation monitoring is required.With the development of satellite remote sensing technology,InSAR(Interferometric Synthetic Aperture Radar,InSAR)technology has been rapidly developed as an important means of deformation monitoring due to its high-precision deformation monitoring capability.It has gradually matured and applied in earthquake monitoring and surface monitoring.It has been paid attention to and applied in deformation monitoring.Taking a hotel in Beijing as a pilot,comparing the measured level results with the data measured by InSAR,analyzing the deformation measurement accuracy of InSAR under different conditions.
