Abstract :
POST (POrtable Submillimeter Telescope) is a submillimeter telescope working in the 500 GHz band. The antenna is a dual-offset Cassegrain type with a diameter of 30 cm. Here we present its performance including the receiver noise temperature, RF noise temperature and far-field antenna beam pattern measured at 462 GHz and 493 GHz respectively. Antenna pointing accuracy is also evaluated. Detailed measurement results will be presented.
