中文摘要：
为优化掩膜区域的相位解缠结果，提出一种改进的掩膜割线相位解缠算法。掩膜区域生成后，直接对非掩膜区域进行相位求解，然后对低质量相位区域采用“消圈”法来最小化掩膜区域相位的不连续性，达到消除传统掩膜割线算法中的解缠“死区”，并保持相位连续性的目的。对InSAR和InSAS干涉图的解缠结果表明：该方法消除了传统掩膜割线法中的解缠“死区”，提高了解缠相位质量。
英文摘要：
In order to optimize the unwrapped result of those mask areas, an improved maskcut phase unwrapping algorithm is proposed. After the mask generation, those nonmask areas are unwrapped directly, then the ＂circle cancelling＂ method is performed during those mask areas to minimize the discontinuity, which can remove those ＂died area＂ and keep the unwrapped result continuous. The tests performed on InSAR and InSAS interferograms show that the improved algorithm removes the ＂died area＂ of the unwrapped result successfully and greatly enhances its quality.
