中文摘要:
      从军事应用及民用领域对合成孔径雷达(SAR)的新需求出发,分析了传统的SAR应对新需求所面临的技术困境;介绍了新体制多输入多输出合成孔径雷达(MIMO-SAR)系统的技术优势和可能应用,以及在实际应用中可能面临的技术瓶颈。最后,重点介绍了同频码分MIMO-SAR技术瓶颈的主要解决方法。
英文摘要:
      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.
