【摘要】 提出了一种利用解缠后的相位信息或相位梯度信息确定形变区域的InSAR形变检测新方法——双轨差分法,阐述了检测原理,设计了检测流程。实验结果表明,双轨差分法能检测形变区域。经比较分析得出,利用解缠后的相位信息能确定形变区域位置和形变量,检测灵敏度较低;利用相位梯度信息仅能确定形变区域位置,检测灵敏度较高。更多还原

【Abstract】 A deformation detection method of interferometric synthetic aperture radar system which is called two tracks differential method was proposed.Unwrapped phase or phase gradient information to confirm deformation area were used in the proposed method.Detection Principle was described and detection flow was designed.Experiment results indicate that two track differential methods could detect deformation area.Comparative analysis shows that it has low sensitivity when unwrapped phase information is used to detect position and size of deformation area;and it has high sensitivity when phase gradient information is used to detect the position of deformation area only.更多还原
