该基线估计方法的有效性。-Baseline Estimation is important for deriving accurate heights in processing of InSAR（Interferometric Synthetic Aperture Radar）. It needs large quantities of ground control points with proper placements to estimate baseline parameters for multiple InSAR data that cover large areas if adopting baseline estimation algorithm for each pair of data. What’s more, there will be great difference between heights derived from different data due to the errors of baseline estimation. A new baseline estimation algorithm with block adjustment considering phase offset was proposed to reduce the needed ground control points and the difference between heights derived from different data. The experiments of baseline estimation with block adjustment were done with multiple pairs of InSAR data obtained by airborne InSAR system researched by Institute of Electronics, Chinese Academy of Sciences. It used less ground control points, and the difference between heights in overlap areas was reduced, as validate

Description: 干涉参数定标对于机载双天线InSAR（Interferometric Synthetic Aperture Radar）系统的大面积高精度数字高程模型（DEM，Digital Elevation Model）获取具有重要意义。为了高效地进行干涉参数定标，本文从双天线InSAR获取DEM的基本原理出发，构建了一种新的考虑干涉相位偏置、基线长度和基线水平角三个干涉参数的外定标模型，设计了外定标模型的未知参数解算方案。利用GPS（Global Position System，全球定位系统）实测的高程控制点对中国科学院电子学研究所自主研制的机载双天线InSAR系统进行了干涉参数定标实验，统计了利用定标后干涉参数反演地面高程的精度，验证了所采用外定标模型及解算方案的正确性和有效性。-It is significant to calibrate interferometric parameters of dual-antenna airborne InSAR（Interferometric Synthetic Aperture Radar）systems for deriving accurate DEM (Digital Elevation Model) with large areas. A new outside calibration model considering phase offset, baseline length and baseline angle was proposed in order to calibrate interferometric parameters effectively, which was induced from the basic theory of DEM deriving from InSAR. And its solution scheme was designed. The outside calibration experiments were done with height control points measured by GPS to calibrate the dual-antenna airborne InSAR system researched independently by Institute of Electronics, Chinese Academy of Sciences. The accuracy of heights derived with calibrated interferometric parameters was calculated, as validated the proposed calibration model and its solution algorithm.

Description: 对于InSAR 系统,当波长较长时,干涉图条纹频率较低,相位解缠容易,但反演的高程精度较低
而当波长较短时,干涉图条纹频率较高,相位解缠困难,但反演的高程精度较高. 为了充分利用多波段
InSAR 干涉相位之间的互补信息,设计了利用中国余数定理的多波段InSAR 相位解缠方法,采用由DEM
仿真的多波段干涉图进行了相位解缠实验,得到了理想的解缠结果,成功解决了因地形起伏较大或基线较长而引起的干涉相位欠采样处的相位解缠难题.-For the InSAR System熏when the wavelength is longer熏the frequency of fringes will be lower熏the
phase unwrapping will be easier熏and the accuracy of derived heights will be lower. However熏when the
wavelength is shorter熏the frequency of fringes will be higher熏the phase unwrapping will be more difficult熏and
the accuracy of derived heights will be higher. In order to make the best use of compensatory information in
multi鄄band InSAR phases熏the phase unwrapping algorithm with the Chinese Remainder Theorem for multi鄄band
InSAR is designed. The multi鄄band interferograms simulated from DEM are applied to do phase unwrapping
experiments. The satisfying phase unwrapping results are obtained. The difficulty in phase unwrapping of sub鄄
sampling interferometric phases due to great hypsography or longer baseline is removed.
