For the problem of radar target three-dimensional scattering centers parameter estimation, a new method that based on state space method and spectrum estimation method (3D-SS-ESPRIT) is proposed. According to the 3D-GTD model theory, we obtained the high-frequency radar target parameter signal model, via constructing generalized Hankel matrix, we estimated 3D scattering centers parameters based on the state space method and reconstructed the high-frequency radar target characteristic data. Numerical simulations show that the proposed method is an efficient and reliable method to estimate these parameters, compared to convention 3D spectrum estimation method, the proposed method gain better estimation, reconstruction property and has better stability.
