New FiLM-GPNet enhances InSAR phase restoration with geometry adaptation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed FiLM-GPNet, a novel geometry-conditioned network designed to improve phase restoration in temporal Interferometric SAR (InSAR) analysis. This network explicitly adapts to variations in acquisition geometries using Feature-wise Linear Modulation (FiLM) and a detailed geometry descriptor. Trained with pseudo-supervision and physics-based regularization, FiLM-GPNet demonstrated significant reductions in temporal residuals and closure errors on InSAR stacks from Hawaii and Western Australia, outperforming the traditional Goldstein filter. The model also showed strong zero-shot generalization capabilities to a distinct dataset from Los Angeles without requiring retraining. AI

IMPACT This research could lead to more accurate and consistent analysis of radar data, improving applications in geology, disaster monitoring, and urban planning.
