摘　　要：合成孔径雷达干涉(Interferometric Synthetic Aperture Radar, InSAR)技术作为地质灾害变形监测的有力手段近年来逐渐被广泛应用。InSAR技术的实现离不开相干性好的地面控制点,以消除大气等环境因素和地形对干涉测量产生的误差。本文为满足InSAR技术对地面控制点的定位精度要求,调研了不同波段哨兵卫星传感器发射电磁波的特性,研究开发了雷达信号增强系统,并开展了室内测试与室外验证工作,结果表明雷达信号增强系统可增强雷达后向反射信号,从而辅助雷达影像定标、配准。Interferometric Synthetic Aperture Radar(InSAR)technology has been widely used as a powerful means for geological disaster deformation monitoring in recent years.The realization of InSAR technology is inseparable from the ground control points with good coherence to eliminate the errors caused by environmental factors such as the atmosphere and terrain on interferometry.In order to meet the positioning accuracy requirements of InSAR technology for ground control points,this paper investigates the characteristics of electromagnetic waves emitted by sentinel satellite sensors in different bands,researches and develops radar signal enhancement systems,and carries out indoor testing and outdoor verification,and the results show that the radar signal enhancement system can enhance the radar backward reflection signal,thereby assisting radar image calibration and registration.
