Abstract：The SNR of part of interferogram over the complex topography in the western China is low, it makes unwrap of wrapped phase difficult. The interferograms over the mountain region in the western China with 9 methods based on pathfollowing, least square and networkflow were unwrapped. The experiment and analysis show that the method of minimum cost flow in irregular network is optimal for unwrapping the SAR interferogram over the western China.
