【摘要】 太赫兹成像采用的成像算法多来自于其他频段已经成熟的成像算法,而针对太赫兹波特性的成像算法还不多见,因此在太赫兹频段形成了成像机理及算法研究的空白。按照经典电磁理论、光学原理对太赫兹成像进行分类,指出了雷达成像与太赫兹成像之间的关系。并通过研究太赫兹雷达目标散射特征,分析了不同太赫兹源的衍射极限成像分辨力。最后,从信号处理的角度介绍了太赫兹雷达信号处理及成像算法的研究现状。更多还原

【Abstract】 The paper points out terahertz imaging algorithm has yet to be developed,in contrast to other matured imaging algorithm.It may be said that there is a "terahertz gap" in the field of imaging algorithm.Then,based on the classification of terahertz imaging,the relationship between radar imaging and terahertz imaging is discussed.The terahertz radar target signature is studied,and the ultimate imaging resolution of different terahertz sources is analysed.Finally,a review of terahertz radar signal processing and imaging algorithm is presented.更多还原
