Biography:
Omar Hadj-Sahraoui is a senior researcher at the Remote Sensing Department of the Algerian Space Agency (ASAL). He holds an Engineering degree and a Magister in Computer Science & Remote Sensing, as well as a PhD with honors from the University of Science and Technology of Oran. He began his career in 1998 as a university lecturer before joining ASAL in 2000, where he has contributed to several national and international research programs. His work includes major projects on solar radiation mapping, natural disaster monitoring, and advanced InSAR processing, with strong expertise in optical–SAR image analysis, DInSAR, coherence enhancement, radar image correction, and GIS tool development. His research interests span optical and SAR image processing, geospatial data fusion, time-series analysis, and geophysical parameter retrieval. He has extensive experience with multispectral, hyperspectral, and radar satellite missions, developing methods for calibration, classification, automation, up/downscaling, and multi-sensor integration. Dr. Hadj-Sahraoui has served on the technical and scientific committees of numerous international conferences and journals, including WSEAS, ICGDA, ICAMCS, ICSSE, and several IEEE and IET publications. He has authored multiple peer-reviewed papers and conference contributions in remote sensing, image processing, and GIS applications for environmental and risk-management studies.
