Abstract

Mapping heterogeneous urban environments using conventional Synthetic Aperture Radar (SAR) backscatter intensity frequently produces classification errors due to spectral similarity between sparse built-up features, bare soil, and dry vegetation a challenge especially acute in semi-arid Deccan Plateau settings. This research presents a dual-path Pol- InSAR fusion framework that integrates polarimetric scattering decomposition and interferometric coherence stability to extract heterogeneous urban signatures over Beed Taluka, Maharashtra (area: 1,561.31 km²). A temporal stack of 69 Sentinel-1 C-band dual- polarization (VV+VH) Interferometric Wide (IW) acquisitions spanning the full annual cycle of 2024 was processed entirely within Google Earth Engine. Coherent scattering pixels were identified using the Amplitude Dispersion Index (ADI
