Chandrayaan-2 | Initial imaging and observations by Dual-Frequency Synthetic Aperture Radar (DF-SAR
Chandraayan-2 is designed to produce greater details about the morphology and ejecta materials of impact craters due to its ability of imaging with higher resolution (2 - 75m slant range) and full-polarimetric modes in standalone as well as joint modes in S and L-band with wide range of incidence angle coverage (9.5° - 35°). In addition, the greater depth of penetration of L-band (3-5 meters) enables probing the buried terrain at greater depths. The L & S band SAR payload helps in unambiguously identifying and quantitatively estimating the lunar polar water-ice in permanently shadowed regions. A convenient approach towards discerning the radar information is to prepare images using two derived parameters, ‘m’ the degree of polarization and ‘δ’ the relative phase between the transmit-receive polarized signals. These parameters are used to generate colour composite images with ‘even-bounce’, ‘volume or diffused’ and ‘odd-bounce’ scatterings of a pixel represented in red (R), green(G), and blue (B) image planes, respectively.
