查询词典 a priori bound

A region superresolution spectrum estimation method based on coventional DFT computation is presented for obtaining one dimensional range profile, which has the advantages of real-time in computation and robustness under clutter and noise background over general superresolution methods. A iterative extropolation method based on both priori knowledge provided by conventional DFT spectrum and matching filtering process of target return data is also presented for range profile processing, which has the advantages of robustness in improving range resolution, suppressing clutter and noise.
