随着星载合成孔径雷达(SAR)技术的快速发展,雷达成像模式在不断更新,成像精度及广度要求在不断提高。为适应发展速度,提高雷达系统的研发效率,降低经济及时间成本,文中设计了一款基于大容量存储的多通道雷达模拟器,能够解决星载大场景下高精度回波数据模拟及存储问题,并用该系统仿真得到准确可靠的实验结果。基于大容量存储的多通道雷达模拟器为星载SAR 系统的研制提供了的更有效的测试手段。

With the rapid development of spaceborne synthetic aperture radar(SAR) technology, the radar imaging mode is constantly updated and the requirements for imaging accuracy as well as breadth are constantly improved. In order to adapt to the developing, improve the efficiency of research and development for radar system and reduce the economy and time, this paper is proposed to design a multi-channel radar simulator based on mass storage, which can solve the problem of simulation and storage of high precision echo data in spaceborne large scene. The multi-channel radar simulator based on mass storage, provides a more effective test method for the development of spaceborne SAR system.
