近年来,在射电天文学、大气科学发展的推动作用下,THz时域光谱技术发展迅速,被广泛地应用于遥感领域。介绍了与THz遥感相关的技术和应用,包括地球观测系统和射电天文学,突出了THz遥感技术与其他学科之间的紧密联系,显示出了巨大的应用前景。美国、欧洲、日本在THz遥感领域起步较早,拥有一些成熟的技术和设备;中国起步较晚,技术上和国际先进水平还有一定差距。 In recent years, under the impetus of radio astronomy and atmospheric science, THz time-domain spectroscopy has developed rapidly and has been widely used in the field of remote sensing. The technologies and applications related to THz remote sensing are introduced, including the earth observation system and radio astronomy, highlighting the close relationship between THz remote sensing technology and other disciplines and showing great application prospect. The United States, Europe and Japan started earlier in the field of THz remote sensing and possess some mature technologies and equipment. Although China started relatively late, there is still a gap between the advanced technology and the international advanced level.
