地面干涉雷达是一种基于微波干涉技术的新型雷达,具有高精度、高分辨率的特点。介绍一种地面干涉雷达系统——微变形监测系统(IBIS),该系统采用步进频率-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。高层建筑的变形监测试验表明,IBIS的精度高,能监测到建筑的微小变形,可真实地反映高层建筑的变形规律。
Ground-based interference radar is a new type of radar based on microwave interference technology, with high precision and high resolution. A ground-penetrating radar system, the Micro-Deformation Monitoring System (IBIS), is introduced. The system uses stepping frequency-continuous wave, synthetic aperture radar and interferometry technology to monitor ground targets dynamically or statically. The deformation monitoring test of high-rise building shows that IBIS has high precision and can detect slight deformation of the building, which can truly reflect the deformation law of high-rise buildings.
