摘要
相位解模糊是影响雷达干涉测量技术应用的一个瓶颈问题,本文提出了采用质量图区域生长对干涉低相干区进行屏蔽并对屏蔽区相位采用移动曲面拟合的干涉图解模糊方法。通过对由多种不同雷达干涉数据获取的干涉图进行解模糊处理,验证了该方法的稳健性和可靠性。
Phase unwrapping is a bottleneck that blocks the applications of interferometric synthetic aperture radar. In this paper, a new phase unwrapping method is presented, which adopts region grow algorithm based on quality map to form shield for low coherence region and adopts mobile surface fitting algorithm in the shield region. The phase unwrapping results of interferograms derived from different interferometric SAR data validate that the new phase unwrapping method is robust and reliable.
