长基线的机载重轨InSAR影像配准方法
An image co-registration method for long-baseline airborne repeat-pass InSAR
摘要
Abstract
The paper is aimed to solve long-baseline airborne repeat-pass interferometric synthetic aperture radar(In-SAR)system survey's difficulties in accurate co-registration and interference avoidance due to the relative deforma-tion between repeat-pass image pairs and the size difference of the ground resolution cells corresponding to homony-my pixels caused by aircrafts' unsteady flight height and flying attitude.The slave images are resampled according to the size of the main image space by high precision relalive positioning.Specifically, based on the precise SAR imaging geometrical model,the first step is calibrating the initial range and flying height by using several ground control point data,and the second step is using high precise relative positioning to calculate the slave image coordi-nates of the master image pixels and resample the slave image with the same size of main image.Experiment used VV-Polarization C-band airborne repeat-pass InSAR images.The resolution of images is 0.5m.The experiment re-sult shows that the proposed method is feasible and suitable for co-registration of long-baseline airborne repeat-pass SAR images.关键词
