Overview
- ISRO made the Level-3C polar mosaic radar products from the Chandrayaan-2 orbiter publicly available via the ISSDC PRADAN portal with visualization through the CH2 MapBrowse platform.
- The dataset synthesizes about 1,400 full-polarimetric L-band observations into 25‑metre‑per‑pixel mosaics covering 80°–90° latitude in both polar regions.
- Chandrayaan-2’s DFSAR is the first instrument to map the Moon in L-band full-polarimetric mode at this resolution, enabling surface and subsurface diagnostics.
- Scientists at ISRO’s Space Applications Centre in Ahmedabad developed indigenous algorithms to produce advanced products characterizing physical and dielectric properties of the regolith.
- Released layers include CPR, SERD, T-Ratio and polarimetric decomposition components that indicate potential subsurface ice, quantify surface roughness and constrain dielectric constants to support landing-site selection and resource planning.
