【摘要】 太赫兹合成孔径雷达（SAR）采用新式雷达技术，具备全天时全天候的工作能力，但目前已有太赫兹SAR的带宽和分辨率均无法满足总体单位的应用需求。设计师以需求为导向，在充分调研与借鉴的基础上，运用头脑风暴法、系统图等质量工具方法，提出多种设计方案，并通过方案论证、仿真、试验等，确定和实施最佳方案，最终宽带高分辨率太赫兹SAR满足顾客提出的带宽≥5GHz和分辨率优于0.1m×0.1m的需求。更多还原

【Abstract】 As a new detection technology, terahertz synthetic aperture radar(hereinafter referred to as SAR) could provide benefits of day-night operation and almost an all-weather capability. Nowadays, the bandwidth and imaging resolution of terahertz SAR cannot meet the requirements. Based on full investigation and reference, we used brainstorming, system diagram and other quality tool methods to propose a variety of design schemes. The best scheme was determined and implemented through project demonstration, simulation and test. Finally, the manufacture task of broad-band high-resolution terahertz SAR system with bandwidth larger than 5GHz and resolution of 0.1m×0.1m was accomplished to meet customer needs.更多还原
