Abstract :
For fully polarimetric wideband radar system, a novel method of radar target recognition using polarimetric feature is proposed. First, polarimetric scattering matrix is obtained from fully polarimetric high resolution range profiles(HRRPs). Then, two different kinds of polarimetric features are extracted by polarimetric target decomposition theorem. At last, K-Nearest Neighbors(KNN) classifier is applied to verify the recognition performance of these two features. The simulation experiments indicate target recognition via polarimetric features can reach a higher recognition performance in different experimental scenarios.
