Pre-HEAT是新南威尔士大学为高原天文台开发的一台20厘米孔径亚毫米波望远镜，配有660千兆赫（450微米）肖特基二极管外差接收器和数字FFT光谱仪。2008年1月，它被部署到南极高原的圆顶A，作为中国极地研究所和中国科学院领导的科学考察的一部分。Dome A可能是世界上地面太赫兹天文学的最佳地点之一，因为那里普遍存在异常寒冷，干燥和稳定的条件。预热是测量450微米的天空不透明度在圆顶A和映射银河平面在13 CO J=6-5线，构成第一次亚毫米测量圆顶A。它正在实地测试其同名的许多关键技术-一个名为HEAT的后续使命：高海拔南极太赫兹望远镜。从穹顶A亚毫米天文学和预热的状态令人兴奋的前景将被提出。
Pre-HEAT is a 20 cm aperture submillimeter-wave telescope with a 660 GHz (450 micron) Schottky diode heterodyne receiver and digital FFT spectrometer for the Plateau Observatory (PLATO) developed by the University of New South Wales. In January 2008 it was deployed to Dome A, the summit of the Antarctic plateau, as part of a scientific traverse led by the Polar Research Institute of China and the Chinese Academy of Sciences. Dome A may be one of the best sites in the world for ground based Terahertz astronomy, based on the exceptionally cold, dry and stable conditions which prevail there. Pre-HEAT is measuring the 450 micron sky opacity at Dome A and mapping the Galactic Plane in the 13CO J=6-5 line, constituting the first submillimeter measurements from Dome A. It is field-testing many of the key technologies for its namesake -- a successor mission called HEAT: the High Elevation Antarctic Terahertz telescope. Exciting prospects for submillimeter astronomy from Dome A and the status of Pre-HEAT will be presented.
