Authors- Deepak Putrevu, Tathagata Chakraborty and DFSAR team, Space Application Center, ISRO Ahmedabad. Radar studies of the lunar surface have so far been restricted to Earth-based radio telescopes and Moon-orbiting sensors operating with limited polarimetry configuration. The Dual-frequency Synthetic Aperture Radar (DFSAR) onboard Chandrayaan-2 (Ch-2) orbiter is the first ever state-of-the-art high-resolution radar system in the lunar orbit. To this Continue Reading »

Author: Ashish Joshi, IIRS An oil spill is one of the worst environmental disasters which affect marine ecosystems due to anthropogenic activities. Oil spills can be detected, monitored, and studied using various types of remote sensing techniques. Synthetic Aperture Radar (SAR) is widely used in oil spill detection due to its all-weather and all-time capabilities. Oil Spills have a smooth Continue Reading »
