Conference Agenda

To explore the lunar surface several studies were carried out with many lunar missions. Continuous efforts were made by many scientists to confirm the presence of water on the lunar surface. Using remote sensing techniques much of the information was obtained from the lunar surface. Synthetic Aperture Radar (SAR) an active sensor, utilizes microwaves frequencies such as L, X, S-bands for analyzing Lunar surface and subsurface. Since, SAR is sensitive to water and has more penetration capability into the lunar surface, chandrayaan-2 mission with Dual Frequency Synthetic Aperture Radar (DFSAR) payload was manifested. DFSAR, a microwave imaging instrument was the first of its kind to utilizes dual frequencies (L and S - Bands) to operate in full polarimetric and hybrid polarimetric modes. In hybrid polarimetry, signals are circularly transmitted and linearly received. DFSAR is the first payload to operate in full polarimetric capability with L-band. In this study, several sites were used Such as Chandrayaan-3 landing site and south pole to carry out the polarimetric analysis. Yamaguchi, H-A- Alpha, and Raney M-Delta and M-Chi decomposition were applied on the datasets and several child parameters are computed.

In this study L-Band Full pol and Hybrid pol data were analyzed on the same site for a better analysis. Yamaguchi four component decomposition was performed on full pol data on lunar south pol. We compared our analysis of full pol data with hybrid pol for estimating the response of circular polarized component interaction with the lunar surface. Polarimetric analysis on Ch-3 landing site, post and pre-landing were contradicting with each other, and this may be due to the lander impact on the Lunar surface. The landing site has almost a flat terrain with few small craters. In this study, we observed that hybrid pol data has almost similar information when compared to full pol data.
