    Abstract:
    Synthetic Aperture Radar (SAR) remote sensing has emerged as a promising tool for soil moisture monitoring, due to its ability to penetrate clouds and measure the moisture content of the soil surface. In recent years, a wide range of SAR-based soil moisture retrieval techniques have been developed, from empirical regression models to physically-based models that incorporate surface roughness and vegetation effects. This review paper provides an overview of the latest advances in SAR-based soil moisture retrieval, covering the different techniques and algorithms that have been proposed, as well as the applications and challenges associated with the use of SAR data for soil moisture monitoring and management. The paper also discusses the limitations and uncertainties of SAR-based soil moisture retrieval, and provides recommendations for future research directions. Overall, this paper aims to provide a comprehensive and up-to-date overview of the state-of-the-art in SAR-based soil moisture retrieval, and to highlight the potential benefits and limitations of this approach for soil moisture monitoring and management.
