One-Dimensional Spectrum Extrapolation for Circular SAR Imaging

摘要：

Two-dimensional resolution and peak sidelobe ratio (PSLR) of circular SAR (CSAR) change with the variation of relative bandwidth is discussed. Based on this discussion, an algorithm using one-dimensional autoregressive (AR) model to extrapolate spectrum data after matched filtering in range direction is presented. The simulation results of CSAR imaging show that the proposed algorithm can improve resolution and decrease PSLR.
