The near-field nonuniform resolution drawback of multi-receiver SAS imaging is addressed and analyzed with simulation results. The maximum resolution degradation is nearly twice of theoretical value, which may lead to improper interpretation in further processing. Two steps of resolution equalization approaches are proposed and validated. Simulation results reveal that the proposed method offers multi-receiver SAS system range independent equal resolution.
