Abstract
Based on the new application demands of Synthetic Aperture Radar(SAR) in the military and civil fields, the technical difficulties faced by traditional SAR system are analyzed to meet the aforementioned new requirements. Then the technical superiority and potential applications are introduced about the new-system Multiple Input Multiple Output SAR(MIMO-SAR), and the technical bottleneck is described in the application for MIMO-SAR. Finally, the main solutions are summarized to resolve the technical dilemma faced by MIMO-SAR working in the same frequency coverage.
