宽频时域太赫兹雷达具有极高的距离分辨能力和信噪比,对于电磁对抗、目标识别和电磁隐身等领域具有十分重要的意义。近年来美、德、丹麦等国相继开展太赫兹雷达研究。目前我国对太赫兹雷达的研究仍处于空白阶段。采用飞秒激光振荡器作为抽运源,首次实现了基于全光导天线的宽频时域太赫兹雷达。并以坦克缩比模型作为被测物体,获得了360°太赫兹雷
Broadband time-domain terahertz radar has very high range resolving power and signal-to-noise ratio, and is of great significance to the fields of electromagnetic countermeasure, target recognition and electromagnetic stealth. In recent years, the United States, Germany, Denmark and other countries have carried out terahertz radar research. At present, China’s research on terahertz radar is still at a blank stage. Using femtosecond laser oscillator as pumping source, the wideband time-domain terahertz radar based on all-optical antenna is realized for the first time. And the tank reduction model as the measured object, obtained 360 ° THz Ray
