N2 - A GTD-based 2D state-space method is presented in this paper for estimating the parameters of the scattering centers on a moving target under the ultra-wideband conditions. Firstly, this method constructs the GTD-based impulse response from the moving target in the state space equation, and then arranges the impulse response of different frequency at different time into a Hankel matrix. Next, the range and the range rate are estimated by using the Hankel matrix singular value decomposition (SVD), which effectively solves the range aliasing problem when the ranges of different scattering centers are overlapped. It occurs in the 1D state space when the range is estimated only. At last, the type parameter and intensity of the scattering center are solved out by this method. The effectiveness of the method is verified by comparing the result of processing the echo data from the rotating conical target with the CRB on parameters estimation.
