摘　　要：使用太赫兹时域光谱技术研究了太赫兹脉冲对模拟沙尘的透射特性,得到不同沙尘条件下信号的透射光谱。同时还进行了沙尘条件下传送成像信号实验,得到比较清晰的像。结果表明太赫兹脉冲能够在沙尘条件下传输太赫兹图像。This paper repotted the characters of Terahertz pulse radiation to stimulant sand-dust storm by using THz- TDS. The tansmission spectra under different condition of stimulant sand-dust storm are obtained. At the same time we experimentalize the tansmission of imaging signal under different condition of stimulant sand-dust storm. Clear images were obtained. Above-mentioned results indicate Terahertz pulse can transmit image under the condition of stimulant sand-dust storm.
