Phase-unwrapping-algorithm
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.)
