遥感图像统计特征在目标辨识、图像配准以及图像分类等任务中扮演着重要角色。传统的统计特征鲁棒性分析一般是基于图像具有同一传感器参数的假设。而在现实任务中，往往需要处理由不同传感器参数拍摄的遥感图像，比如不同波长或入射角度等。传感器参数不同会导致图像灰度与表象特征不同，进一步会影响到统计特征表达。因此有必要系统研究常用统计特征与传感器参数之间的相关性，从而实现更加鲁棒的图像处理与分析。本文研究了目前常...
INSAR技术在地形测绘以及地表形变测量监测中的巨大潜力已被广泛承认，但是由于受到时空失相关、大气相位变化等因素的影响，干涉质量往往不能得到保证，极大的限制了这项技术的实际应用。为了能够更好的解决常规干涉测量中的难题，SAR干涉点目标技术近年来得到了快速的发展。本文通过深入研究干涉点目标的相位模型，提出了基于空间搜索的邻近点目标干涉相位差解缠方法，用以计算点目标的地形残差和线性形变，以及分离点目标...
