多波段InSAR的CRT相位解缠方法
Phase unwrapping algorithm with CRT for multi-band InSAR
摘要
Abstract
For the InSAR System, when the wavelength is longer, the frequency of fringes will be lower, the phase unwrapping will be easier, and the accuracy of derived heights will be lower. However, when the wavelength is shorter, the frequency of fringes will be higher, the phase unwrapping will be more difficult, and the accuracy of derived heights will be higher. In order to make the best use of compensatory information in multi-band InSAR phases, the phase unwrapping algorithm with the Chinese Remainder Theorem for multi-band InSAR is designed. The multi-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-sampling interferometric phases due to great hypsography or longer baseline is removed.关键词
