一种GNSS-DInSAR技术集成的角反射装置
摘要：
一种GNSS‑DInSAR技术集成的角反射装置，属于矿山地表形变监测的角反射装置。该角反射装置由基座、旋转抬升装置、对中杆和角反射器四部分组成；利用GNSS技术获取角反射器顶点三维坐标，一方面可验证DInSAR技术的形变监测精度，另一方面可将已知精确空间位置的角反射器用于优化和提高地理编码精度，同时也可用作相位解缠参考点和干涉像对基线优化，作为GNSS技术和DInSAR技术的联系纽带，实现GNSS与DInSAR技术的有效集成。优点：(1)结构简单，成本低，占地空间小，安装方便，缩短了野外角反射装置的安装时间。(2)角反射装置俯仰角调整由角度测量转换为距离测量，提高了安装精度。(3)实现GNSS和角反射装置的集成，GNSS所测坐标即为角反射装置顶点的坐标，提高GNSS作业效率。
摘要（英）：

The invention provides a corner reflecting device integrating GNSS and DInSAR technology and belongs to mine ground surface deformation monitoring. The corner reflecting device is composed of a pedestal, a rotation and lifting device, a centering rod and a corner reflector. Three dimensional coordinates of a top point of the corner reflector are obtained by utilizing the GNSS technology. On one hand, the deformation monitoring precision of the DInSAR technology can be verified; on the other hand, the corner reflector with known precise spatial position can be used for optimizing and improving geographic encoding precision, as a phase unwrapping reference point and for interference image pair reference line optimization. The scheme acts as a connection bond for the GNSS technology and the DInSAR technology and realizes effective integration of the GNSS technology and the DInSAR technology. The corner reflecting device provided by the invention has advantages that (1) the structure is simple, the cost is low, the space occupancy is small, the mounting is convenient and the field mounting time is shortened; (2) the pitch angle adjustment of the corner reflecting device is realized through range measurement instead of angle measurement, so that the mounting precision is improved; (3) the integration of the GNSS technology and the corner reflecting device is realized, the coordinates measured by using the GNSS technology is the coordinates of the top point of the corner reflecting device, so that GNSS operation efficiency is improved.
