摘要
与微波雷达和红外探测器相比,太赫兹技术应用于雷达将带来高距离分辨率、强穿透力、低截获率与强抗干扰能力等众多优势,是目前太赫兹技术的主要应用方向之一。在分析太赫兹雷达特点与优势的基础上,介绍了目前主要太赫兹雷达系统的研究与进展情况,并进一步对太赫兹雷达涉及的目标散射特性技术研究与成像技术研究进行了进展回顾与评述,由此指出了太赫兹雷达研究中的一些关键技术与主要研究内容。结合太赫兹雷达在空间目标探测与反导拦截中的应用,仿真分析了太赫兹拦截导引头的关键性能指标,为太赫兹雷达技术的应用发展提供参考与借鉴。
Radar in terahertz regime has great advantages compared with microwave radar and infrared detector, such as high range resolution, strong penetrating ability, low intercept probability and strong anti-interference ability, etc. On the basis of analysis of characteristics and advantages of terahertz radar, research progress of terahertz radar systems reported recently is introduced first. Then, study of target scattering characteristics and radar imaging technologies in terahertz regime is reviewed and commented. Some of the key technologies and main research directions related to the terahertz radar are pointed out correspondingly. Key parameters of terahertz radar system are analyzed and simulated concerned with military applications of space target detecting and radar seeker, which helps to provide reference for the application development of terahertz radar.
