Abstract:In this paper, a new parameters estimation method of scattering centers with high resolution range profile (HRRP) is proposed . The features of HRRP describe the radial distribution of object scattering center, which is a good candidate for radar object recognition. Firstly, the parameter estimation of scattering centers is transformed to a problem of spare reconstruction. Then, the design method of measurement matrix and selection method of sparse parameters are discussed. In order to improve the stability of sparse solution, a positional warp approach is em-ployed to construct the dictionary matrix. To improve the efficiency of algorithm, the model order and sparse pa-rameter are established by Bayesian information criterion. Extensive experiments validate the feasibility and stabil-ity of our proposed algorithm.
