Abstract of Speech

A state of the art Synthetic Aperture Radar, NISAR, jointly being developed by ISRO and NASA, will be ready for launch in 2021 end by India. This unique mission has been conceptualized to provide L and S band space-borne SAR data freely to global community with both high resolution and larger swath having full-polarimetric capability and high repeat cycle, as well as 12 days Interferometric modes of operation for various science studies and number of applications. Huge amount of data collected by NISAR mission will address the critical issues of forest biomass estimation and monitoring of carbon fluxes; surface deformations; icesheet monitoring, dynamics of snow, shoreline change; coastal and ocean parameters; geological mapping and sub-surface feature detection, disaster management related studies involving global as well as Indian scientific community. For effective utilization of the data, various software and algorithms will be developed and it will also enhance the knowledge base with polarimetric SAR data analysis in Indian research community. Towards development of the spaceborne system, Space Applications Centre, ISRO has also developed an airborne L & S band SAR which has started collecting the data over various Indian sites, identified by researchers across the country, covering different scientific themes.
