A Phase Unwrapping Approach Based on the Branch-Cut Method and Finite Element Method for Interferometric SAR

  • 摘要: 该文提出了一种基于枝切法和有限元法的干涉SAR相位图展开方法。该方法针对不同质量的相位区域采用不同的方法:首先利用枝切法准确性高和一致性好的特点,使用该方法展开面积最大的一块缠绕相位区域;然后在较好的边值条件下利用最小二乘意义下的有限元法求解剩余区域的展开相位。仿真和实测数据处理结果表明,该方法很好地克服了枝切法不能得到完整解和最小二乘法对于相位坡度欠估计的缺点,且与其它方法相比具有较高的精度。
