The full-polarimetric (FP) imaging mode has enriched the information of Synthetic Aperture Radar (SAR) data, and has been widely used in remote sensing applications, e.g. for land cover classification, environmental monitoring,or target detection. However, the application of FP SAR has been constrained by the design and maintenance complexity, power consumption, image swath, and data-downloading rate. Compact Polarimetric (CP) SAR systems not only overcome the drawbacks of FP SAR system, but also keep the FP information to a certain extent. Preliminary results are available in several fields, such as forest parameters estimation, feature classification and target detection. This paper provides an overview of compact polarimetric SAR system fundamentals, describes the methods of FP information reconstruction and decomposition, and summarizes its main research achievements of the last decade. At the end, we give its development trends.
