Abstract：To deal with the clutter suppression issue in the moving target detection for the near-shore water regions with azimuth multichannel SAR systems, the multichannel steering vector of the ambiguous clutter is derived, and the multichannel signal model of the near-shore water regions in image domain is established. Based on the derived steering vector and the established signal model, ambiguous clutter suppression methods suitable for the near-shore water regions are proposed. The impact of the spatial ambiguity which is induced by the sampling with multiple channels, on the ambiguous clutter is analyzed. Then, the simulation analysis of the Ground Moving Target Indication (GMTI) performance for the near-shore water region is given. The validities of the proposed methods are verified by the simulation results.
