Multithreading approach for focusing module performance optimization of Small BAseline Subset processing chain

Small BAseline Subset (SBAS) technique, developed by CNR -IREA, is a DInSAR approach allowing to detect Earth's surface deformation and to analyse their temporal evolution. To process SAR acquisitions using this technique large number of data is required and a sophisticate elaboration is necessary. A sequential code implementation leads to processing times that don't meet market constraints, very demanding in terms of processing time delivery. This work, in collaboration with CNR-IREA, demonstrates multi-threads potentiality to reduce processing time of SBAS chain, using multicore capabilities of new platforms in cluster environment. Development of a robust, efficient and flexible concurrent application for focusing module is described.
