摘要
太赫兹雷达散射截面(RCS)测量技术是当前太赫兹重要的应用技术之一。利用太赫兹源,不仅可以测得目标太赫兹波段的RCS,还可以通过对缩比模型的RCS测量,获得微波波段全尺寸目标的RCS值。基于RCS定义及测量的一般要求,介绍了国外太赫兹RCS测量的主要成果;重点介绍三类测量装置及测量目标;给出部分代表性的测量结果。最后分析了利用飞秒激光器抽运晶体的太赫兹时域谱系统、CO2激光抽运太赫兹激光器的逆合成孔径雷达系统和信号合成器的相干探测系统在工作频率、待测目标尺寸和小型化等方面的特点。为我国太赫兹RCS测量技术的发展提供技术借鉴。
Abstract
Terahertz radar cross section (RCS) measurement is one of the most important techniques in terahertz applications. By using terahertz sources, the RCS of the targets and scale-models at terahertz band can be obtained, through which RCS of the full size targets at microwave band can also be calculated. Based on the definition of RCS and general requirements in the experiment, the main results of the terahertz RCS measurements abroad are provided. Three kinds of measuring facilities and targets and some typical measuring results are also emphasized. In the end, the characteristics in work frequency, size and miniaturization of targets and something else related when using terahertz time-domain spectrums system of femtosecond laser pumped crystal, inverse synthetic aperture radar system of CO2 laser pumped terhertz laser and coherent detection system with signal synthesizer are analyzed respectively, too. It helps to provide reference for the development of terahertz RCS measurement technology in our country.
