| description | The invention discloses a double-base SAR (Synthetic Aperture Radar) phase synchronization interference suppression method based on sparse low-rank recovery, and belongs to the technical field of radars. The method comprises the following steps: step 1, establishing a bistatic SAR two-dimensional mixed synchronization signal matrix model # imgabs0 # subjected to radio frequency interference pollution according to a bistatic synthetic aperture radar SAR phase synchronization process principle; 2, when a radio frequency interference signal matrix # imgabs2 # and an ideal synchronization signal matrix # imgabs3 # in the # imgabs1 # respectively meet two constraint conditions of sparsity and low rank, executing the step 3; 3, processing the # imgabs4 # by using a partial singular value decomposition and sparse low-rank matrix recovery algorithm, and separating a radio frequency interference signal matrix # imgabs5 # and an ideal synchronization signal matrix # imgabs6 # to obtain an ideal synchronization signal m |
