摘要
相位解缠作为SAR干涉测量数据处理中的一个关键步骤,受到越来越广泛的关注,出现了各种各样的算法。但现有的相位解缠算法仍无法解决高噪声问题,由此导致噪声区域的误差传递到其它区域,产生全局误差,从而影响相位解缠精度。针对这种情况,本文根据区域增长解缠算法的特点,利用最小不连续法来全局优化区域增长策略,从而实现区域增长的全局优化解缠,并取得了较理想的解缠结果。
As the key step of lnSAR data processing, many phase unwrapping algorithms were introduced. But these algorithms had problems in high noisy interferogram. In view of the situation, this paper, based on the characteristics of quality - guiding unwrapping algorithm, uses minimum discontinuity algorithm to wholly optimize the quality - guiding strategy, and finally the global optimizing unwrapping of quality - guiding is realized with a better un-wrapping result.
