Abstract:
In this study, we examine Sentinel 1 (S1) Synthetic Aperture Radar (SAR) time series to detect and assess pest-induced vegetation anomalies. The S1 time series was analysed using multiple SAR-based data as vegetation indices. The analyses were performed on a case study located in Castel Porziano (central Italy), chosen due to its significant impact from Toumeyella Parvicornis (TP) in recent years. The area of Follonica, which is not yet affected by TP, was used as a comparison. Our goal is to identify patterns associated with TP in the statistical features of S1 data. The methodology employed is the well-established Fisher-Shannon analysis, which characterizes the temporal dynamics of complex time series using two informational measures: the Fisher Information Measure (FIM) and the Shannon Entropy Power (SEP). Analysis of the Receiver Operating Characteristic (ROC) curve indicates that these two measures are highly effective in distinguishing between infected and healthy sites.
