Selection of stable point wise targets is an important procedure in multi-temporal SAR images interpretation and application in monitoring surface deformation. Several targets selection methods based on amplitude and coherence approaches have been proposed in recently years. However, these two approaches have their own defects. Amplitude Selection (AS) method require enough data to ensure the accuracy of identification result, Coherence Selection (CS) method depends on spatial baseline values used to generate interferograms. In this work we propose a robust selection strategy of stable pointwise targets based on small baseline subsets to reduce spatial deccorelation phenomena, and uses small SAR dataset. The experiment results are presented using ERS data SAR acquired on Houdh Berkaoui region in south-east of Algeria.
