摘　　要：干涉SAR的相位展开是干涉SAR应用中的一项重要技术。本文改进了区域增长的相位展开算法,提出了新的增长规则。新规则扩大了信息提取范围,从而提高了相位估计的精度和展开过程的稳健性。仿真结果验证了方法的有效性和实用性。The phase-unwrapping is an important technology in the InSAR application. A new growing rule is presented in this paper and the phase-unwrapping method based on the region-growing is improved. The new growing rule increases the accuracy and solidity of the phase estimation by enlarging the region of obtaining information. Simulation results validate the availability.

关 键 词：干涉SAR 相位展开 区域增长
