Decorrelation is one of the key restrictive factors when the InSAR technique is used to derive the parameters of inland glaciers in China.This paper has compared the coherence patterns between different perpendicular baselines,terrain slopes and wavelengths from both the theoretical and the experimental results based on analyzing the factors leading to the interferometric spatial decorrelation. Taking the Dongkemadi Glacier of western China as the study area,the authors analyzed the different coherence patterns of the Dongkemadi Glacier by using C-band ENVISAT/ASAR and L-band ALOS/PALSAR data. The quantitative result is also given. The results indicate that the capability of the coherence by ALOS/PALSAR repeat-pass pairs is higher than that of the coherence by ENVISAT/ASAR pairs. The L-band ALOS/PALSAR data are more fit for extracting the parameters of the inland glacier.
