随着现代大地测量技术的飞速发展,不同观测几何、不同时间、空间尺度等更高精度、更丰富的形变观测数据也随之增多,这极大地提高了地表形变的监测能力,从而为研究地壳构造运动和地壳物理特点提供数据支撑,为地质灾害预警预测提供了重要的手段。一般地,在大地测量领域,GNSS和InSAR技术在分析解译地表形变,认识地壳形变方面提供了重要的数据保障。虽然GNSS技术能提供高精度的形变观测,但是GNSS观测的空间分辨率低;故高空间分辨率的InSAR观测很好地弥补了这一缺陷。然而,InSAR观测只能得到一维视线向上地表的变化,无法反映三维坐标系下各方向的真实地表形变,从而易导致对地表形变信息产生误解,难以揭示复杂的形变特征。因此,论文以GNSS和InSAR观测提取三维地表形变为核心,创新性地开展了如何削弱插值误差影响,如何精确确定各类数据权比,以及如何统一各类数据之间的参考基准等研究工作,从而完善三维形变提取理论和方法,获取高精度的三维地表形变场。主要研究内容如下。
