A Review on PolSAR for FOPEN Applications

Abstract: PolSAR has become a significant focus of research due to its wide-ranging applications in structural monitoring, foliage penetration, and target detection. Despite its potential, work on FOPEN remains limited and often inconsistent, largely because forest environments differ considerably in structure and density. Integrating PolSAR with FOPEN techniques enhances the ability to detect obscured targets by exploiting polarization dependent scattering information that conventional radars cannot provide. This review outlines the limitations of traditional radar architectures, particularly their reduced capability for accurate image formation in complex environments, and highlights how SAR and PolSAR systems address these challenges through improved resolution, diverse polarization modes, and enhanced interpretability. A comprehensive examination and comparison of existing literature is presented, synthesizing current methods and insights relevant to PolSAR based FOPEN studies. Keywords: Radar, SAR, PolSAR, Imaging, FOPEN.
