About the Webinar

Synthetic aperture radar (SAR) sensors acquire high- resolution images of earth surface even under cloudy cover conditions. The penetration capability of instrument allows to see through dense or sparse vegetation or below the forest. Penetration within a medium also allows to see below the dry sand surface. In recent time, SAR data is available from different satellites at a given frequency ranging from P band to X band. A few of the missions like NISAR and Chandrayaan-2 provide dual frequency and polarimetric data. Thus, a variety of data set is available for the user community in exploring potential benefits for various applications. In this lecture, we present results on the evaluation of multiparametric SAR data for different applications like soil moisture, agriculture, forestry, disaster management, landcover studies and lunar water ice detection.

 

About the Speaker

Dr. Shiv Mohan is an eminent Indian scientist and educator internationally recognized for his pioneering contributions to microwave remote sensing. During a distinguished 33-year career at the Indian Space Research Organisation (ISRO), he played a transformative role in developing India’s spaceborne SAR and microwave remote sensing application capabilities.

At ISRO, he led several landmark national and international research initiatives, including the joint ISRO–DLR airborne radar and radiometer campaigns, multifrequency scatterometer/radiometer experiments, and collaborative projects awarded to him through global Announcements of Opportunity from NASA/DLR, ESA, JAXA, and the Italian Space Agency. His leadership was instrumental in establishing ISRO’s first comprehensive SAR Applications Programme.
He served as the principal architect and Project Director of India’s pioneering RISAT Utilization Programme, laying the foundation for operational SAR applications in the country. Dr. Mohan was a key scientist for the Chandrayaan-1 Mini-SAR mission, contributing to the lunar water-ice detection model, and played a major role in defining the Dual-Frequency SAR payload for the Chandrayaan-2 mission.

After retiring from ISRO, Dr. Mohan joined the Physical Research Laboratory (PRL), Ahmedabad, where he advanced research on dual-frequency SAR for lunar water-ice detection, regolith depth estimation, and crater morphology, significantly enriching India’s planetary science capabilities.
Dr. Mohan has served on more than 70 high-level ISRO technical committees, including those for RISAT-1, Chandrayaan-1/2, and the upcoming Venus mission. He has authored over 320 scientific publications, delivered around 190 tutorials, guided 28 postgraduate students, and written two notable books: Chandrayaan-1 Mini-SAR (2012) and Smart Buildings and Cities Using Remote Sensing and GIS (2025).

His exceptional scientific and professional contributions have earned him numerous prestigious honours, including the Indian National Remote Sensing Award (1995), the Elsevier Outstanding Reviewer Award (2015), and the IEEE GRSS Outstanding Service Award (2022)—making him the first Indian scientist to receive this global recognition. He is also the recipient of the Outstanding Space Scientist Award (2025) from the Prestige Institute of Management and Research, Indore, and the Samaj Bandhu Award (2025) from Prantik Earth Care, Shantiniketan. Earlier in his career, he served as a Visiting Scientist at DLR, Germany (1980, 1981), and as Chief Scientist to the Government of Haryana (1998–2001).

Dr. Mohan has made foundational contributions to the growth of the IEEE Geoscience and Remote Sensing Society (GRSS) in India. He initiated India’s flagship GRSS-supported conference, InGARSS, serving as General Chair in 2020 and 2021, established the virtual GRSS Image Analysis Lab, and founded the IEEE GRSS Gujarat Chapter. He continues to serve the community as the IEEE GRSS Liaison for India (2019-2023. 2025), IEEE GRSS Liaison (2024) for AP region. He also served as an Executive Committee member of IEEE Gujarat (2021–2025) and the IEEE India Council (2023). Currently, Dr. Shiv Mohan is a Visiting Professor at various educational institute, consultant to Geospatial industry and technical director in startup geospatial
