摘要
随着社会的发展,人们对大型、高层建筑物的振动、变形的监测要求越来越高。而与此同时,由于建筑物体积和高度的不断变大,传统的测量手段已经不能很好地满足变形监测的要求。近年来,微波干涉测量技术以其特有的"非接触性"与"实时性"等优势,逐步成为人们对大型、高层建筑物进行非接触式变形监测的手段之一。地面干涉雷达系统——微变形监测系统(IBIS),采用步进频率-连续波、合成孔径雷达和干涉测量技术,能对地面目标作动态或静态监测。
With the development of society,people of large,high-rise building vibration,deformation monitoring have become increasingly demanding.Meanwhile,the building size and height becomes larger and larger,the traditional means of measurement has not well positioned to meet the requirements of deformation monitoring.In recent years,microwave interferometry with its unique ＂non-contact＂ and ＂real time＂ and other advantages,and gradually become a large,high-rise building deformation monitoring of non-contact one of the means.Ground radar system interference-Micro Deformation Monitoring System（IBIS）,the system uses step frequency-continuous wave,synthetic aperture radar and interferometry,ground targets can be dynamic or static monitoring.
