Phase unwrapping is an important part in the process of InSAR signal processing. When ground-based SAR is used for multistage mountain slope deformation monitoring, the mountain slopes are always separated by slope ladders. So the interferometric phase of every slope must be unwrapped by path-following methods respectively. In view of the multistage slope phase unwrapping, this paper proposed a mask...
River detection from SAR images plays an important role in civilian applications. A new method for river detection is proposed in this paper, which includes fuzzy clustering, wavelet transform and using snake model. River area can be extracted by clustering and morphological processing. Then the edge of river is extracted with the wavelet modulus maximum method (WTMM), and is smoothed by the snake...
The method of moving target detection based on subimage cancellation for single-antenna airborne SAR is presented. First the subimage is obtained through frequency processing is pointed out. The imaging difference of a stationary objects and moving object in the subimage based on the frequency division is analyzed from the fundamental principle. Then the developed method combines the shear averaging...
