Understanding Sentinel-1 backscatter response to sugarcane yield variability and waterlogging

Sentinel-1 observes the whole globe every 12 days (6 when both satellites were operational) and provides a wealth of data relevant to agriculture. Sugarcane cultivators could potentially benefit from these by using them assist operational management practices. However, first, thorough understanding is needed backscatter its behavior over sugarcane canopies. In this study, we aimed improve how responds yield variability waterlogging. order do so focused on an irrigated plantation in Xinavane, Mozambique. analysis presented, assessed different polarizations, their ratio, benchmarked against optical indices passive microwave observations seasons. With help large dataset, analyzed relates sucrose We found VV related stalk development, most important reservoir for accumulation. addition, season with reported waterlogging, radar showed delay crop development. Further presence water underneath canopy caused increase all polarizations cross ratio (CR). The results imply that contains information waterlogging under as well development stalk. By isolating quantifying impact backscatter, it will be possible further quantify identify simultaneously.
