In this paper a comparison between two typologies of point-like scatterers in SAR images, named Persistent Scatterers (PSs) and Coherent Scatterers (CSs) is proposed. The PSs are detected through the analysis of large stack of data, implying their temporal stability, and have been principally used for SAR interferometric applications. Differently, CSs are detected in single SAR images through their spectral correlation properties and have been applied for parameters extraction by means of polarimetric data. The main research in this paper is focused to the CSs temporal stability and to the result obtained, for image time series and with both categories of point-like scatterers, concerning Line of Sight (LOS) displacement measurements.
