Based on High Resolution Transmission(HITRAN) database and the fact that the imaging spectrometer Visible and Infrared Thermal Imaging Spectrometer(VIRTIS) on the "Venus Express" has observed thermal emissions from the surface of Venus, infrared atmosphere windows adapted to the Venus atmosphere model are simulated, and then the terahertz atmosphere windows of Venus are analyzed. By establishing scientific object that realizing all-weather remote sensing for exploration Venus surface, advantages of sensing the atmosphere windows of Venus in terahertz are given, and idea of multi-function Venus sensing is put forward.
