SAR Log-Ratio Anomaly

Per-pixel log10 ratio of a single post-event SAR backscatter scene against a pre-event temporal baseline mean. Inputs are SAR backscatter in decibels (Sentinel-1 GRD convention); output is dimensionless. The anomaly map feeds the burn-detection CNN in the SAR4Wildfire (Ban & Zhang 2020) recipe and generalises to flood, deforestation, and landslide pipelines. Polarization-agnostic — the recipe selects VH or VV.
