| Abstract: | A polarimetric radar can be used to obtain the 2×2 scattering matrix information of radar target. Comparing with conventional radars, the polarimetric radar has an advantage that its measured target information is much larger, and it has some important applications in many fields. In this paper, the authors summarize the recent advances of target polarimetric feature extraction, including target decomposition based feature extraction approach and the straight approach to target feature extraction. In addition, the existed problems are commented and the prospect forecast is given. |
