宽带高分辨太赫兹合成孔径雷达研制中质量工具方法的应用

Application of Quality Tool Methods for Development of Broad-band High-resolution Terahertz Synthetic Aperture Radar

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。

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 X 0.1m was accomplished to meet customer needs.
