We present in this work some advances of the Differential SAR Interferometry (DInSAR) technique referred to as Parallel Small BAseline Subset (P-SBAS) approach, allowing us to effectivel y process the recently available L band SAR images acquired by the Argentinian SAOCOM-1 constellation. This activity has been carried out within the DInSAR-3M project, co-funded by the Italian Space Agency, which is aimed to develop technical solutions for the joint exploitation of multi -frequency (X-, C- and L - band) and multi-platform (spaceborne and airborne) DInSAR measurements. The main goal is the generat ion of surface deformation time series and corresponding mean displacement velocity maps, spatially and temporally dense, for the multi-scale analysis of natural and anthropogenic phenomena. The assessment of the developed advances has been carried out by processing several SAOCOM -1 SAR datasets acquired over Italy between 2019 and 2022.
